Types of Lyme Disease

Lyme disease is a bacterial infection you get from the bite of an infected black‑legged tick. The tick feeds on a small animal (often mice) that carries Borrelia bacteria, then later bites a human. The bacteria move from the tick’s saliva into the person’s skin. A spreading red rash called erythema migrans (often a “bull’s‑eye” shape, though it can be a simple expanding red patch) is the classic early sign. Without treatment, the bacteria can travel through the body and irritate nerves (causing facial weakness or shooting pains), the heart (causing slow or irregular heartbeats), and the joints (causing swelling, especially in the knee). Doctors diagnose Lyme using symptoms, exam findings, and blood tests done with a two‑step (two‑tier) testing process. Antibiotics cure the infection in most people. Some people have lasting tiredness or pain after treatment; this is called post‑treatment Lyme disease syndrome (PTLDS) and usually improves over time with supportive care.

Lyme disease is an infection you get from the bite of a tiny, hard-bodied tick (often Ixodes ticks, sometimes called deer ticks or black-legged ticks). The tick carries a spiral-shaped bacterium called Borrelia burgdorferi (in North America) or closely related Borrelia species (in Europe and parts of Asia). When an infected tick feeds on your blood for many hours, the bacteria can move from the tick’s gut into your skin and then travel through your body.

Lyme disease usually starts with early signs on the skin—a spreading circular rash called erythema migrans (“EM”)—and flu-like symptoms. If it is not treated in time, the infection can spread to the nervous system (causing nerve pain, facial weakness, meningitis), to the heart (causing heart block—a problem with the heart’s electrical wiring), and to the joints (causing swollen, painful knees and other joints). With timely antibiotics, most people fully recover. Some people can have lingering symptoms (such as fatigue, pain, or brain fog) even after the germs are gone; this is called post-treatment Lyme disease syndrome (PTLDS). It’s real and distressing, but it does not mean the infection is still active; prolonged or repeated antibiotics generally don’t help those lingering symptoms and can cause harm. Care then focuses on rehabilitation and symptom control.

How Lyme Spreads

1. Ticks carry the bacteria. Certain ticks (black‑legged or deer ticks in North America; Ixodes ricinus and Ixodes persulcatus in Europe/Asia) can carry Borrelia.
2. Ticks feed slowly. They attach and feed for many hours. The longer a tick is attached, the higher the chance of passing bacteria.
3. People often don’t feel the bite. Ticks are small, especially the nymph (teenage) stage, so people may not notice.
4. Bacteria enter through the skin. From there, the bacteria can stay local (rash) or spread through the body.

People who live, work, or play in or near wooded, brushy, or grassy areas in places where Lyme is common have higher risk. Late spring through early fall is the main season because nymph ticks are active and very small. Children, hikers, campers, landscapers, park rangers, and pet owners are often exposed.

Types of Lyme Disease

Doctors may use several “type” labels to describe Lyme, depending on timing, body system involved, or the Borrelia species in different regions. Here are the most common, explained in simple terms.

A. By Timeline (Stages)

1. Early localized Lyme: Days to weeks after the bite. Usually one large, expanding red rash (erythema migrans) plus flu‑like symptoms.
2. Early disseminated Lyme: Weeks to months after the bite. The bacteria spread. People may have multiple rashes, facial nerve weakness (Bell’s palsy), meningitis‑like headache/neck stiffness, shooting nerve pains, or heart rhythm problems (Lyme carditis).
3. Late Lyme (late disseminated): Months to years after the bite. The most common problem is Lyme arthritis—repeated or persistent swelling of large joints, especially the knee. Some people may have chronic nerve pain or numbness.

B. By Organ System

1. Cutaneous (skin) Lyme: Erythema migrans and, in Europe, a long‑lasting thin skin condition called acrodermatitis chronica atrophicans.
2. Neurologic Lyme (neuroborreliosis): Meningitis‑like illness, facial palsy, radiculopathy (shooting pains, numbness), or rarely brain/spinal cord inflammation.
3. Cardiac Lyme (Lyme carditis): Heart block (slow heart rate because the electrical signal is delayed), chest discomfort, lightheadedness, or fainting.
4. Articular Lyme (Lyme arthritis): Intermittent or persistent swelling and pain in the joints, typically the knee.

C. By Bacterial Species (Regional)

1. North America: Borrelia burgdorferi sensu stricto is the main species.
2. Europe: Borrelia afzelii (more skin problems) and Borrelia garinii (more nerve problems) are common.

D. After Treatment

1. Post‑Treatment Lyme Disease Syndrome (PTLDS): Ongoing fatigue, body aches, or “brain fog” after proper antibiotic treatment, without active infection. Symptoms usually improve with time and supportive care.

Causes and Risk Factors

Note: Strictly speaking, the cause is an infected tick bite. The items below expand on real‑world risk factors that make a bite or infection more likely.

1. Being bitten by a black‑legged tick: The only direct cause—this tick can carry Borrelia bacteria.
2. Living or visiting endemic areas: Regions where Lyme is common (for example, parts of the northeastern and upper midwestern U.S., and parts of Europe/Asia).
3. Outdoor work or hobbies: Forestry, landscaping, farming, hiking, camping, hunting, or field research.
4. Tick‑heavy seasons: Late spring, summer, and early fall when nymph ticks are active.
5. Tall grass, brush, and leaf litter exposure: Ticks wait on low vegetation and grab onto passing people or pets.
6. Not using tick repellents: Skipping DEET, picaridin, or permethrin‑treated clothing raises risk.
7. Bare skin outdoors: Shorts, short sleeves, and open shoes expose more skin for ticks to bite.
8. No tick checks after being outside: Missing attached ticks lets them feed longer and pass bacteria.
9. Delayed tick removal: The longer the tick is attached (often >24–36 hours), the higher the risk.
10. Improper tick removal: Squeezing the tick’s body or using heat/chemicals may increase exposure to saliva.
11. Pets that roam outdoors: Dogs and cats can carry ticks into the home.
12. Wooded home surroundings: Yards bordering forests or brush increase tick contact.
13. Rodent‑friendly yard features: Stone walls, woodpiles, and bird feeders attract mice—key hosts for ticks.
14. High deer populations: Deer help adult ticks reproduce and spread in the environment.
15. Mild winters and climate change: Longer warm seasons expand tick range and activity.
16. No protective landscaping: Lack of mulch barriers, short lawns, and clean play areas increases risk.
17. Travel to endemic regions: Visiting areas with Lyme without taking precautions.
18. Children playing on the ground: Kids often play in grass and brush where ticks wait.
19. Crowded trails or edges: Ticks cluster along path edges and animal trails where people brush past.
20. Not laundering outdoor clothes hot/drying high heat: Ticks can survive on clothing unless heat‑dried.

Common Symptoms

1. Expanding red rash (erythema migrans): A growing red patch at or near the bite. It may be warm but usually not very painful or itchy. It can look like a bull’s‑eye but does not have to.
2. Fever and chills: Mild to moderate fever early on, feeling “flu‑ish.”
3. Fatigue: Unusual tiredness that can be strong and last days to weeks.
4. Headache: Often steady and can be worse with light or movement, especially with meningitis‑like irritation.
5. Neck stiffness: Pain or stiffness when bending the neck forward can hint at meningeal irritation.
6. Muscle aches: General body aches like a viral illness.
7. Joint pains: Achy joints that may move from one joint to another (migratory) early on.
8. Swollen joints (Lyme arthritis): Later, one or more large joints—often a knee—can become puffy, stiff, and painful.
9. Swollen lymph nodes: Tender lumps in the neck, armpits, or groin as the immune system reacts.
10. Facial weakness (Bell’s palsy): One side of the face droops; you may have trouble closing the eye or smiling.
11. Shooting nerve pains: Sharp, electric, or burning pains from nerve irritation (radiculopathy), often worse at night.
12. Numbness and tingling: Pins‑and‑needles in the face, arms, or legs.
13. Heart palpitations or dizziness: Feeling your heart skip or beat slowly/irregularly; may feel faint if heart block occurs.
14. Memory or concentration problems (“brain fog”): Trouble focusing, slowed thinking, or forgetfulness.
15. Eye symptoms: Redness, light sensitivity, or blurry vision from inflammation (conjunctivitis or uveitis—less common).

Important notes: Not everyone gets the rash, or they may not notice it. Symptoms can start days to weeks after a bite, and different people may have different combinations. Many other illnesses can mimic Lyme, which is why testing and clinical judgment matter.

Diagnostic Tests

Doctors do not rely on any single test. They combine your story (possible exposure), symptoms, physical exam, and tests. Early on, blood tests may be negative because the immune system has not made enough antibodies yet. That is why the rash and exposure history are so important.

A. Physical Exam

1. Full‑body skin check for erythema migrans: The clinician looks for a large, expanding red patch that is at least several centimeters across. Finding this rash in someone with likely tick exposure is usually enough to diagnose early Lyme without waiting for blood tests.
2. Vital signs (temperature, pulse, blood pressure, oxygen): Fever supports an active infection. A very slow pulse can signal heart block from Lyme carditis.
3. Lymph node exam: The clinician gently feels for tender, enlarged nodes near the rash or in common areas (neck, armpits, groin). Swollen nodes support infection.
4. Heart and lung exam: Listening for heart rate and rhythm changes (too slow/irregular) and checking for chest discomfort that could suggest carditis.

B. Manual (Bedside) Tests

1. Facial nerve function test: You are asked to raise eyebrows, close eyes tight, puff cheeks, and smile. Weakness on one side suggests Bell’s palsy related to Lyme.
2. Neck flexion test for stiffness: Gently bending the neck forward; stiffness or pain can hint at meningeal irritation in neuroborreliosis.
3. Knee joint assessment (range of motion and bulge test): The clinician moves the knee to check stiffness and uses gentle pressure to see if fluid gathers (effusion), which supports Lyme arthritis.
4. Romberg balance test: Standing with feet together and eyes closed; swaying or loss of balance can reflect sensory nerve issues sometimes seen with neuroborreliosis.

C. Lab and Pathological Tests

1. First‑step antibody test (EIA/ELISA): A screening blood test that looks for antibodies against Borrelia. If this is negative early, it may be repeated in a few weeks.
2. Second‑step immunoblot (Western blot) or a second EIA (modified two‑tier testing): If the first test is positive or equivocal, a confirmatory test is done. Traditional two‑tier testing uses IgM and IgG immunoblots; modified two‑tier testing uses two different EIAs. A positive two‑step result supports the diagnosis.
3. C6 peptide EIA: A particular EIA that targets a conserved Borrelia protein piece (C6). It works as a first‑ or second‑step test depending on the lab’s algorithm.
4. Acute and convalescent serology: If early tests are negative but suspicion is high, blood may be drawn again 2–4 weeks later to look for new antibodies (seroconversion) or rising levels.
5. PCR for Borrelia DNA in synovial fluid (Lyme arthritis): Detects bacterial genetic material in joint fluid. Especially helpful when the knee is swollen.
6. Cerebrospinal fluid (CSF) analysis: A spinal tap can show higher white blood cells (usually lymphocytes) and protein in neuroborreliosis. Glucose is usually normal.
7. CSF‑to‑serum antibody index for Borrelia: Compares Lyme antibodies in CSF to blood; a high index supports antibody production inside the nervous system, which points to neuroborreliosis.
8. General inflammation and rule‑out labs (ESR/CRP, complete blood count, liver tests): These are non‑specific but support inflammation and help exclude other diseases.

D. Electrodiagnostic Tests

1. Electrocardiogram (ECG/EKG): Measures the heart’s electrical activity. In Lyme carditis, it can show different degrees of atrioventricular (AV) block, which may make the heart beat very slowly. Continuous monitoring (telemetry or Holter) may be used if symptoms are worrisome.
2. Nerve conduction studies and electromyography (NCS/EMG): Assess how well nerves and muscles carry signals. In Lyme‑related neuropathy, results can show slowed or reduced nerve signals.

E. Imaging Tests

1. MRI of brain and/or spine: Used when neurologic Lyme is suspected. MRI can show inflammation of cranial nerves, meninges, or nerve roots (enhancement), or help exclude other causes of symptoms.
2. Echocardiogram (heart ultrasound): If carditis is suspected, this test checks heart pumping and looks for inflammation‑related changes. It complements the ECG.

Non-pharmacological treatments

These are things beyond prescription drugs that can help you recover, ease symptoms, or prevent problems. They do not replace antibiotics when antibiotics are indicated, but they work alongside them.

1. Early tick removal (correct technique)
   Description: Use fine-tipped tweezers to grasp the tick close to the skin and pull upward with steady pressure; clean the area after.
   Purpose: Reduce the chance of the bacteria passing from tick to you.
   Mechanism: Borrelia usually needs many hours of attachment to transmit; the sooner you remove, the lower the risk.

2. Wound care after tick removal
   Description: Wash with soap and water or alcohol; watch the site for expanding redness.
   Purpose: Prevent local infection and help you notice a developing EM rash.
   Mechanism: Clean skin lowers bacterial contamination and daily checks improve early detection.

3. Rest during acute illness
   Description: Prioritize sleep and reduce exertion during fever and acute symptoms.
   Purpose: Support your immune system.
   Mechanism: Sleep and reduced stress hormones improve immune signaling and recovery.

4. Hydration and balanced electrolytes
   Description: Drink water regularly; consider oral rehydration if feverish or sweating.
   Purpose: Replace fluids; reduce headaches and fatigue.
   Mechanism: Adequate fluid volume supports circulation and temperature control.

5. Anti-inflammatory self-care (cold/heat)
   Description: Ice packs for swollen joints; gentle heat for muscle aches.
   Purpose: Ease pain and swelling.
   Mechanism: Cold reduces local blood flow and inflammatory chemicals; heat relaxes muscle spasm.

6. Joint protection and activity pacing
   Description: Short, frequent activities with rest breaks; avoid high-impact exercise during joint flares.
   Purpose: Prevent worsening joint pain and protect cartilage.
   Mechanism: Limits mechanical stress while inflammation settles.

7. Physical therapy (PT)
   Description: Guided range-of-motion, strengthening, and balance training.
   Purpose: Restore mobility, reduce pain, and prevent long-term stiffness after Lyme arthritis or neuropathy.
   Mechanism: Gradual loading reduces inflammation and promotes muscle and nerve recovery.

8. Occupational therapy (OT)
   Description: Adapt daily tasks; ergonomic advice; energy-conservation strategies.
   Purpose: Maintain independence and reduce fatigue.
   Mechanism: Optimizes body mechanics and reduces overuse of inflamed joints.

9. Gentle aerobic conditioning (graded)
   Description: Once fever and acute pain settle, start low-impact movements (walking, stationary bike), increasing slowly.
   Purpose: Combat deconditioning, fatigue, and mood symptoms.
   Mechanism: Improves mitochondrial function, blood flow, and endorphins.

10. Mind-body techniques
    Description: Breathing exercises, mindfulness, guided imagery, or yoga adapted to energy levels.
    Purpose: Reduce stress, improve sleep and pain coping.
    Mechanism: Lowers sympathetic arousal and pain perception pathways.

11. Cognitive pacing & cognitive rehab strategies
    Description: Use planners, spaced breaks, single-tasking, and memory aids if “brain fog” is present.
    Purpose: Support concentration during recovery.
    Mechanism: Compensates for reduced working memory while neuroinflammation settles.

12. Nutrition for recovery
    Description: Balanced meals with lean proteins, fiber, fruits/vegetables, and healthy fats.
    Purpose: Support immune function and tissue repair.
    Mechanism: Provides amino acids, micronutrients, and anti-inflammatory phytonutrients.

13. Sun protection while on photosensitizing antibiotics
    Description: Shade, clothing, sunscreen (especially with doxycycline).
    Purpose: Prevent painful sunburns and skin damage.
    Mechanism: Blocks UV that triggers exaggerated reactions with certain drugs.

14. Compression and elevation for swollen joints
    Description: Elastic sleeves, gentle compression, and leg elevation.
    Purpose: Reduce joint effusion and discomfort.
    Mechanism: Improves venous/lymphatic return and reduces intra-articular pressure.

15. Sleep hygiene
    Description: Fixed bedtime, cool dark room, limit screens before sleep.
    Purpose: Improve energy and pain tolerance.
    Mechanism: Stabilizes circadian rhythm and inflammatory cytokine profiles.

16. Smoking cessation
    Description: Stop tobacco/nicotine products.
    Purpose: Improve immune function and circulation.
    Mechanism: Reduces oxidative stress and improves microvascular blood flow.

17. Alcohol moderation/avoidance during acute therapy
    Description: Avoid or limit alcohol while ill and on antibiotics.
    Purpose: Protect liver, prevent drug interactions, improve sleep quality.
    Mechanism: Reduces hepatic strain and sedative-additive effects.

18. Probiotic-rich foods during/after antibiotics
    Description: Yogurt with live cultures, kefir, kimchi, or doctor-approved probiotics.
    Purpose: Reduce antibiotic-associated diarrhea and gut discomfort.
    Mechanism: Restores beneficial gut flora diversity.

19. Return-to-work/school planning
    Description: Temporary accommodations (reduced hours, flexible deadlines).
    Purpose: Maintain function without setbacks.
    Mechanism: Matches workload to current energy levels during recovery.

20. Psychological support
    Description: Education, counseling, or support groups if anxiety or low mood occur.
    Purpose: Reduce distress; improve adherence and outcomes.
    Mechanism: Normalizes the experience and gives practical coping tools.

Regenerative / stem cell” drug

This is important: There are no approved stem-cell drugs or regenerative biologics to treat Lyme disease. Using stem cells or immune-suppressing biologics for Lyme outside of a clinical trial is not recommended and can be dangerous. Below are six categories people ask about—what they are, and why they are not standard care.

1. Stem cell infusions (various sources)
   Status: Not approved for Lyme; no good evidence of benefit.
   Risks: Infections, immune reactions, emboli, high cost.
   Bottom line: Avoid outside regulated trials.

2. Intravenous immunoglobulin (IVIG)
   Status: Sometimes used for severe immune-mediated neuropathies (rare), not a Lyme infection cure.
   Mechanism: Modulates immune responses.
   Bottom line: Only for specific immune conditions under specialists; not for routine Lyme.

3. Monoclonal antibodies / biologic immunosuppressants
   Status: Not indicated for Lyme infection; could worsen infection control.
   Bottom line: Not used to treat Lyme.

4. Platelet-rich plasma (PRP) injections
   Status: Sometimes used for orthopedic issues; no evidence for Lyme arthritis infection.
   Bottom line: Not a treatment for Lyme bacteria.

5. Hyperbaric oxygen therapy
   Status: Studied for various conditions; no high-quality evidence for Lyme, potential risks (ear/sinus injury).
   Bottom line: Not standard of care.

6. Long-term combination antibiotics as “immune reset”
   Status: Multiple trials show no sustained benefit for PTLDS; higher harms.
   Bottom line: Not recommended outside trials.

Procedures/surgeries

Surgery is rare in Lyme disease. These procedures address complications:

1. Temporary transvenous cardiac pacing
   What it is: A temporary pacing wire to keep the heart rate safe during severe Lyme carditis with high-grade heart block.
   Why done: Prevent fainting and risk from very slow heart rates while antibiotics work.
   Outcome: Most people recover conduction in days to weeks; the wire is then removed.

2. Permanent pacemaker (rare)
   What it is: A small device implanted to keep heart rhythm steady.
   Why done: Only if heart block does not recover (unusual) after infection is treated.
   Outcome: Provides long-term rhythm support.

3. Arthrocentesis (joint fluid drainage)
   What it is: Needle removal of excess knee fluid.
   Why done: Reduce pressure and pain; obtain fluid to test for inflammation/PCR.
   Outcome: Symptom relief; sometimes repeated during flares.

4. Arthroscopic synovectomy (select cases)
   What it is: Keyhole surgery to remove inflamed joint lining after antibiotics if arthritis remains very stubborn.
   Why done: Reduce chronic swelling when inflammation persists without active infection.
   Outcome: Can improve function in refractory cases.

5. Lumbar puncture (diagnostic procedure)
   What it is: A spinal tap to analyze cerebrospinal fluid.
   Why done: Evaluate suspected Lyme meningitis/radiculitis and guide therapy.
   Outcome: Helps choose correct treatment; not a “cure,” but crucial for diagnosis.

Prevention strategies

1. Know your risk areas: Wooded, brushy, leaf-litter zones in spring–fall.

2. Clothing barriers: Long sleeves, long pants tucked into socks; light colors to spot ticks.

3. Tick repellents: Use DEET (20–30%), picaridin, or IR3535 on exposed skin.

4. Permethrin-treated clothing/gear: Kills ticks on contact; do not apply to skin.

5. Stay on paths: Avoid brushing against tall grass/brush when hiking.

6. Daily tick checks: Shower within 2 hours of outdoor activity; check entire body (scalp, behind knees, armpits, groin).

7. Prompt, proper removal: Use fine tweezers; avoid burning or twisting.

8. Landscape control at home: Clear leaf litter, create gravel/wood-chip borders, keep grass short.

9. Protect pets: Vet-recommended tick collars/spots to reduce ticks in the home.

10. Post-exposure prophylaxis when appropriate: Ask about single-dose doxycycline within 72 hours for high-risk bites.

When to see a doctor

• You develop a spreading circular rash (especially >5 cm) days to weeks after a tick bite.

• You have fever, chills, headache, stiff neck, muscle/joint pain, or unusual fatigue after being in tick areas.

• You notice facial droop, severe headache, neck stiffness, shooting pains, or numbness/weakness.

• You have chest pain, shortness of breath, palpitations, dizziness, or fainting.

• Your knee or other joint becomes warm, swollen, and stiff, especially if swelling is large or recurring.

• You’re pregnant, immunocompromised, or a child with possible Lyme—treatment nuances matter.

• You have lingering symptoms after completing antibiotics—get a plan for rehab and symptom management.

What to eat and what to avoid

1. Eat: lean proteins (fish, poultry, legumes) to help tissue repair.

2. Eat: colorful fruits and vegetables (antioxidants, vitamins) daily.

3. Eat: whole grains for steady energy and fiber.

4. Eat: healthy fats (olive oil, nuts, seeds; fish for omega-3s).

5. Drink: plenty of water or oral rehydration fluids during fever.

6. Avoid: excess alcohol, especially while on antibiotics (liver stress, sleep disruption).

7. Avoid: ultra-processed foods high in sugar and trans fats (worsen inflammation).

8. Avoid: very high-oxalate supplements without need if you have kidney issues.

9. Be cautious: grapefruit or St. John’s wort with certain meds (drug interactions); ask your clinician.

10. If on doxycycline: take with a full glass of water; avoid lying down right after; separate from iron, calcium, magnesium supplements by 2–3 hours to avoid reduced absorption.

Frequently asked questions

1. Do I always get a bull’s-eye rash?
   No. Many do, but not everyone. Some rashes are uniformly red or occur in hard-to-see places.

2. Can a tick bite make me sick right away?
   Transmission risk is low in the first 24 hours; risk rises the longer the tick is attached.

3. What if my blood test is negative but I have a classic rash?
   Doctors treat based on the rash; early tests can be negative in the first week.

4. Is doxycycline safe for kids?
   Short courses are commonly used in children for Lyme; dosing is weight-based. Clinicians balance risks and benefits.

5. What about pregnancy?
   Amoxicillin (or cefuroxime) is often preferred. Always involve obstetric care for individualized treatment.

6. Can I get Lyme from another person or pet?
   No—it’s not contagious person-to-person. Pets don’t transmit Lyme directly, but they can bring ticks indoors.

7. Do I need IV antibiotics for every case?
   No. Most cases (like EM) are treated with oral antibiotics. IV is for specific severe cases (neurologic, cardiac, refractory arthritis).

8. What is PTLDS?
   Post-treatment Lyme disease syndrome: ongoing fatigue, pain, or cognitive issues after proper antibiotics. Managed with rehab and symptom care; prolonged antibiotics don’t help.

9. Can I donate blood after Lyme?
   Generally not while symptomatic or on treatment. Check with your blood service for their current rules.

10. Is there a vaccine?
    As of now, no licensed human vaccine is widely available. Candidates are being studied; check with health authorities for updates.

11. If I pull off a tick, should I always take antibiotics?
    Not always. A single dose of doxycycline is considered for high-risk bites (right tick species, attached long enough, in a high-incidence area, and within 72 hours of removal).

12. What if I’m allergic to penicillin and can’t take doxycycline?
    Cefuroxime may still be possible if your allergy is not a severe immediate reaction; otherwise azithromycin is a backup (less effective). Your clinician will decide safely.

13. How long until I feel better?
    Many feel better in days to a couple of weeks. Joint swelling may take weeks to settle, even after bacteria are cleared.

14. Can Lyme come back after treatment?
    Relapses of active infection after proper treatment are uncommon. Lingering inflammation can cause symptoms that improve over time without more antibiotics.

15. Are “chronic Lyme cures” online reliable?
    Be cautious. Many products and prolonged antibiotic plans lack evidence and can be harmful. Stick with guideline-based care.
