Parsonage–Turner Syndrome (PTS)

Parsonage–Turner syndrome (PTS) — also called neuralgic amyotrophy or idiopathic brachial neuritis — is a sudden inflammation of nerves in the shoulder and upper arm (the brachial plexus and nearby nerves). It usually starts with very severe, burning pain in one shoulder or arm. After days to weeks, the pain settles and is replaced by weakness, muscle wasting, and trouble lifting or moving the arm. Some people also have numb patches or a winging shoulder blade from serratus anterior weakness (long thoracic nerve). Symptoms often begin after a “trigger,” such as a viral illness, surgery, intense exercise, or (less often) vaccination or childbirth. Most people slowly improve over months to 2–3 years, but recovery can be incomplete. A hereditary form (hereditary neuralgic amyotrophy) exists and can recur more often.

Parsonage–Turner syndrome (PTS) is a nerve problem that starts suddenly with very strong pain in the shoulder or upper arm. After a few days or weeks, the pain eases, but the person notices weakness and loss of muscle in the shoulder, arm, or hand. This happens because some of the nerves that control arm and shoulder movement get inflamed and injured. PTS most often affects only one arm, but it can involve both. Many people are first told they might have a “pinched nerve in the neck,” but PTS is different: the injury is usually in the network of nerves that travels from the neck into the shoulder and arm (the brachial plexus) or in specific branches of those nerves. Cleveland Clinic+1

What is actually going on?

In PTS, the immune system is thought to attack parts of these nerves, often after a trigger such as an infection, a vaccination, surgery, heavy exercise, or childbirth. This immune attack damages the nerve fibers (axons). Because motor fibers are hit the hardest, weakness shows up more than numbness. The illness often has three phases: a sudden severe pain phase, a weakness/atrophy phase, and a slow recovery phase. Cleveland Clinic+1

Other names

Doctors use several names for the same condition. You may hear:

• Neuralgic amyotrophy – “neuralgic” means nerve pain; “amyotrophy” means muscle loss.

• Brachial neuritis / brachial plexus neuritis / idiopathic brachial plexus neuropathy – inflammation or injury of the brachial plexus without another obvious cause.

• Parsonage–Turner syndrome (PTS) – the eponym from two physicians who described it in detail in 1948. Cleveland Clinic

Types

1. Idiopathic (classic) neuralgic amyotrophy – the common, non-inherited form with a single sudden attack after a trigger; pain first, then weakness. Lippincott Journals

2. Hereditary neuralgic amyotrophy (HNA) – a genetic form that runs in families, usually autosomal dominant. People have repeated attacks and may be affected at a younger age. Many families have changes in the SEPT9 gene. Orpha+1

3. Mononeuropathic (single-nerve) variant – only one branch is involved (for example the long thoracic nerve causing winged scapula; the suprascapular nerve causing trouble with lifting/rotating the arm; or the anterior interosseous nerve causing pinch weakness). PubMed

4. Multifocal plexus involvement – several nerves or trunks are affected in a patchy way; this is common in PTS and helps tell it apart from a single “pinched nerve.” Medscape

5. Bilateral or recurrent disease – both sides can be involved, and some people have more than one attack over time; recurrence is more common in HNA. Cleveland Clinic

6. Variants with special nerves – sometimes the phrenic nerve (breathing muscle) or intercostal nerves (chest wall) are affected, causing shortness of breath or chest wall pain/weakness. Cleveland Clinic

Causes and triggers

These are not always “direct causes.” Most act as triggers that set off an immune reaction in someone who is susceptible.

1. Recent viral illness – common cold-type viruses may be followed by PTS as the immune system calms down and mistakenly attacks nerves. Cleveland Clinic

2. Hepatitis E virus (HEV) – strongly linked in published studies; PTS can be severe and sometimes affects both sides. Testing is worthwhile if there was recent hepatitis or unexplained liver-test changes. PMC+1

3. SARS-CoV-2 (COVID-19) infection – case series and reviews describe PTS after COVID-19, likely through immune mechanisms. SAGE Journals

4. Other specific viruses – reports include Coxsackie B, parvovirus B19, mumps, HIV, and others. Cleveland Clinic

5. Bacterial infections – less common, but illnesses like Lyme disease have been reported before PTS-like attacks. (Doctors usually test for these when history fits.) Medscape

6. Vaccination – PTS has been described after flu and COVID-19 vaccinations; this appears to be a rare immune response, not nerve damage from the needle itself. SAGE Journals

7. Recent surgery – especially around the shoulder/neck or general surgery; immune stress and positioning may both play roles. Cleveland Clinic

8. Regional anesthesia or nerve block – occasionally reported prior to an attack; thought to be a trigger in susceptible people rather than a direct injury. Medscape

9. Heavy or unaccustomed exercise – intense shoulder girdle or overhead activity has preceded attacks in some cases. Cleveland Clinic

10. Trauma to shoulder or neck – even minor trauma may be a trigger, with symptoms starting later as the immune system reacts. Medscape

11. Pregnancy and the postpartum period – immune and hormonal shifts can be triggers around delivery. Cleveland Clinic

12. Autoimmune diseases – conditions like lupus or vasculitis can occur with PTS; these may raise the chance of an immune attack on nerves. Cleveland Clinic

13. Connective-tissue disorders – for example Ehlers–Danlos syndrome; joint laxity and tissue differences may contribute. Cleveland Clinic

14. Radiation therapy – rarely, PTS-like attacks are reported after radiation. Cleveland Clinic

15. Lumbar puncture (spinal tap) or contrast dye exposure – uncommon associations noted in clinic lists of risk factors. Cleveland Clinic

16. Genetic predisposition (SEPT9) – in HNA, attacks are triggered by many of the same events, but the tendency runs in families. Orpha

17. Thyroid disease – autoimmune thyroid problems sometimes travel with other immune nerve issues; doctors often screen for this in unclear cases. Medscape

18. Diabetes – can coexist with PTS and complicate recovery; glucose issues also affect nerves generally. Medscape

19. After a neck or shoulder injury with cervical imaging that looks normal – when imaging does not explain the pain/weakness pattern, PTS becomes more likely. Medscape

20. No clear trigger – in many people, nothing obvious is found, yet the illness follows the classic pattern. Cleveland Clinic

Symptoms

1. Sudden, severe shoulder or upper-arm pain – often one-sided, very intense, and worse at night; it may wake you from sleep. Cleveland Clinic

2. Pain that lasts days to weeks, then eases – the first phase is painful; as pain fades, weakness becomes the main problem. Cleveland Clinic

3. Weakness in shoulder muscles – trouble lifting the arm, reaching overhead, or holding objects out in front. Cleveland Clinic

4. Weakness in elbow or hand – depending on which nerve branch is affected (for example pinch weakness with anterior interosseous nerve involvement). PubMed

5. Muscle wasting (atrophy) – the shoulder or arm may look smaller over weeks to months. Cleveland Clinic

6. Winged scapula – the shoulder blade sticks out, especially with a wall push-up, due to long thoracic nerve involvement. Cleveland Clinic

7. Abnormal reflexes – biceps, triceps, or brachioradialis reflexes may be reduced on the affected side. Cleveland Clinic

8. Numbness or tingling – can occur but is usually milder than the weakness and pain. Cleveland Clinic

9. Stiffness or reduced range of motion – pain and weakness lead to difficulty moving the shoulder normally. Cleveland Clinic

10. Partial shoulder dislocation (subluxation) – weak muscles can let the joint slip, causing aching or clicking. Cleveland Clinic

11. Color or temperature changes in the hand – sometimes the hand looks red or mottled or feels cool from abnormal circulation. Cleveland Clinic

12. Swelling of the hand – less common, but may occur during the painful phase. Cleveland Clinic

13. Shortness of breath – rare, from phrenic nerve involvement affecting the diaphragm. Cleveland Clinic

14. Fatigue during daily arm use – simple tasks feel tiring because muscles are weak and must work harder. Medscape

15. Recurrence of similar attacks – some people experience later episodes, especially in hereditary cases. Cleveland Clinic

Diagnostic tests

A) Physical exam

1. Inspection for asymmetry and muscle wasting
   Your clinician looks for hollowing around the shoulder (supraspinatus/infraspinatus fossa), a drooping shoulder, or visible winging of the scapula. These patterns suggest which nerve branches are injured and help separate PTS from joint problems. PubMed

2. Active vs. passive range of motion
   In PTS, moving the shoulder yourself is limited by pain and weakness, but the clinician can often move the joint farther than you can on your own. This mismatch points to a nerve/muscle problem rather than a frozen joint. Cleveland Clinic

3. Sensory map and reflex testing
   Light touch and pinprick are checked in the arm and hand, and reflexes (biceps, triceps, brachioradialis) are compared side to side. PTS often shows reduced reflexes and patchy sensory change, consistent with selective nerve involvement. Cleveland Clinic

4. Scapular rhythm observation
   While you lift and lower the arm, the examiner watches how the shoulder blade moves. Early and excessive winging suggests long thoracic nerve palsy, a common PTS pattern. Cleveland Clinic

B) Manual tests

5. Wall push-up test (for winged scapula)
   Pushing against a wall makes the inner edge of the shoulder blade pop out if the long thoracic nerve is weak. This quick test flags scapular stabilizer weakness from PTS. Cleveland Clinic

6. “OK sign” pinch test (for anterior interosseous nerve)
   You’re asked to make an “OK” circle with thumb and index finger. With AIN palsy (a PTS pattern), the circle collapses into a triangle because the tip-pinch is weak. PubMed

7. Resisted external rotation (for suprascapular/infraspinatus)
   The clinician resists as you rotate your forearm outward at the side. Weakness suggests suprascapular nerve involvement, common in PTS and different from rotator cuff tears in pattern and associated nerve signs. PubMed

8. Spurling maneuver (to help rule out cervical radiculopathy)
   Gentle neck extension and side-bending with axial pressure usually worsens true pinched-nerve neck pain but is often negative in PTS. A negative Spurling supports PTS when the history fits. Medscape

C) Lab and pathological tests

9. General blood work (ESR/CRP, complete blood count, metabolic panel)
   These may be normal or mildly raised. They mainly look for other conditions (infection, inflammation, systemic illness) that could mimic or trigger nerve injury. Medscape

10. Infection testing when suspected (including Hepatitis E)
    If there was recent hepatitis, travel, or unexplained liver-enzyme elevation, doctors may order HEV IgM/IgG and other infection panels because HEV is a known PTS trigger. PMC

11. Autoimmune screening (e.g., ANA, ANCA, thyroid antibodies)
    When history suggests an immune disorder, these tests help detect conditions that can accompany or imitate PTS and may guide broader treatment. Medscape

12. Genetic testing for SEPT9 (when HNA is suspected)
    If there is a strong family history or repeated attacks, testing for SEPT9 variants can confirm hereditary neuralgic amyotrophy. Orpha

D) Electrodiagnostic studies

13. Nerve conduction studies (NCS)
    NCS show how fast and how strongly nerves carry signals. In PTS, results often point to axonal damage in specific branches rather than a single root, helping separate PTS from a neck pinched nerve. Medscape

14. Needle electromyography (EMG)
    EMG samples selected muscles to look for denervation (fibrillations/positive sharp waves) and reduced recruitment that match the weak muscles. The pattern is patchy and fits particular nerves (for example, suprascapular or long thoracic). Medscape

15. Serial EMG (repeated after 3–6 weeks)
    Because denervation signs take time to appear, a repeat EMG can confirm the diagnosis and document reinnervation during recovery. Medscape

16. Phrenic nerve and diaphragm testing (if shortness of breath)
    Special NCS or EMG of the diaphragm may be used when breathing symptoms suggest phrenic involvement. Cleveland Clinic

E) Imaging tests

17. MRI of shoulder/brachial plexus
    MRI helps rule out rotator-cuff tears, tumors, or disc disease and may show denervation edema in affected muscles during the early phase. Cleveland Clinic

18. Magnetic resonance neurography (MRN)
    MRN can show “hourglass-like” constrictions in the involved nerves—an imaging marker now commonly reported in EMG-confirmed PTS and related to severe axonal injury. PubMed+1

19. High-resolution nerve ultrasound
    Ultrasound can identify focal nerve swelling or constriction and is increasingly used because it is fast, safe, and can be repeated to watch recovery. PMC

20. Cervical spine MRI (differential diagnosis)
    This scan looks for a cervical radiculopathy or spinal cord problem. A normal study in the face of classic symptoms pushes the diagnosis toward PTS. Cleveland Clinic

Non-pharmacological treatments (therapies and others)

1. Education and reassurance
   Purpose: reduce fear, guide safe activity, set recovery expectations.
   Mechanism: when you understand the pain-then-weakness pattern and slow nerve regrowth, you avoid over-protecting the arm and reduce stress-driven pain amplification. Clear advice on what helps (gentle mobility, posture, pacing) prevents secondary problems like frozen shoulder and deconditioning.

2. Acute pain plan and pacing
   Purpose: get through the pain storm safely.
   Mechanism: use scheduled analgesics, short rest, supported positions, and time-limited activity bursts. Pacing breaks the pain–spasm–fear cycle and protects sleep.

3. Protected positioning (short-term sling or pillow support)
   Purpose: calm pain and guard vulnerable muscles.
   Mechanism: offloading the shoulder (elbow supported, pillow under arm, sling only briefly) reduces traction on inflamed nerves. Stop sling as soon as pain allows to prevent stiffness.

4. Sleep optimization
   Purpose: improve healing and pain control.
   Mechanism: regular sleep hours, side-lying with pillows under the painful arm, limit late caffeine, and consider a bedtime routine. Good sleep lowers pain sensitivity and supports nerve recovery.

5. Heat and ice
   Purpose: simple pain relief.
   Mechanism: heat relaxes muscle spasm before gentle movement; ice calms flares after activity. Short, frequent sessions (10–15 minutes) are often better than long ones.

6. Transcutaneous electrical nerve stimulation (TENS)
   Purpose: non-drug pain relief.
   Mechanism: gentle electrical input competes with pain signals (“gate control”), may reduce muscle guarding, and can help during the acute phase.

7. Early gentle range-of-motion (ROM)
   Purpose: prevent frozen shoulder and maintain joint nutrition.
   Mechanism: pain-free pendulums and assisted ROM keep the capsule from tightening while nerves recover.

8. Scapular setting and postural retraining
   Purpose: restore shoulder blade control, reduce winging.
   Mechanism: low-load activation of serratus anterior and lower trapezius (e.g., wall slides, “plus” drills) realigns the scapula, improving mechanics and comfort.

9. Progressive strengthening (later phase)
   Purpose: rebuild lost muscle safely.
   Mechanism: start with isometrics and closed-chain work; advance slowly to resistance bands/weights. The program follows nerve recovery and avoids pain spikes.

10. Nerve-gliding (nerve mobilization) as tolerated
    Purpose: reduce mechanosensitivity.
    Mechanism: careful sliders (not aggressive tensioners) move the nerve within its bed, potentially improving tolerance to stretch without provoking pain.

11. Occupational therapy (OT) and activity adaptation
    Purpose: keep independence in daily tasks.
    Mechanism: task modification, joint protection strategies, energy conservation, and adaptive tools (reacher, jar openers) maintain function while strength returns.

12. Workstation and job modifications
    Purpose: prevent symptom provocation at work.
    Mechanism: adjust chair height, keyboard/mouse placement, armrests, and reduce overhead or heavy tasks on the affected side; spread loads across the week.

13. Bracing or taping for scapular winging
    Purpose: support weak serratus/shoulder blade.
    Mechanism: scapular braces or kinesiology taping can hold the scapula closer to the chest wall, improving comfort for activities and therapy.

14. Hydrotherapy/aquatic therapy
    Purpose: earlier movement with less pain.
    Mechanism: water buoyancy unloads the limb, allowing ROM and light resistance without high strain.

15. Breathing, relaxation, and mindfulness
    Purpose: reduce pain amplification and muscle tension.
    Mechanism: slow breathing, body scans, and brief daily mindfulness lower sympathetic arousal and can reduce perceived pain intensity.

16. Cognitive-behavioral pain skills
    Purpose: better coping and consistency.
    Mechanism: CBT reframes unhelpful thoughts (“I will never recover”), builds pacing skills, and supports adherence to rehab.

17. Graded motor imagery / mirror therapy (selected cases)
    Purpose: help stubborn movement-related pain.
    Mechanism: brain-based retraining (left/right recognition, imagined movements, mirror exercises) can reduce central sensitization.

18. Acupuncture (adjunct)
    Purpose: additional pain relief for some people.
    Mechanism: likely neuromodulation and endogenous opioid release. Evidence is mixed; use as a complement, not a replacement.

19. Dry needling or trigger point therapy
    Purpose: reduce protective muscle spasm in surrounding muscles.
    Mechanism: brief needling or pressure resets tight bands and may improve ROM; should be gentle and combined with exercise.

20. Peer support and education groups
    Purpose: reduce isolation, share practical tips.
    Mechanism: hearing realistic timelines and strategies from others with PTS improves confidence and adherence.

Dietary molecular supplements

1. Omega-3 (EPA/DHA) — 1–2 g/day combined EPA+DHA with meals.
   Function/mechanism: anti-inflammatory lipid mediators (resolvins/protectins) may reduce neuroinflammation and support general cardiovascular health.

2. Alpha-lipoic acid — 300–600 mg/day.
   Function: antioxidant and metabolic cofactor; used in diabetic neuropathy research to reduce burning pain and oxidative stress.

3. Acetyl-L-carnitine — 500–1000 mg 1–2×/day.
   Function: mitochondrial support and nerve regeneration signals; some neuropathy studies show modest benefit.

4. Vitamin B12 (methylcobalamin) — oral 1000 μg/day or periodic injections if deficient.
   Function: myelin and axonal health; correct deficiency to support nerve repair.

5. Benfotiamine (B1) — 150–300 mg/day.
   Function: fat-soluble thiamine improves glucose handling and may reduce advanced glycation products relevant to nerve stress.

6. Vitamin D3 — dose per level (often 1000–2000 IU/day; replete deficiency with clinician guidance).
   Function: immune modulation and musculoskeletal health; correct low levels.

7. Magnesium (e.g., glycinate) — 200–400 mg elemental/day.

Immunity-booster / regenerative / stem-cell–type options

These are not standard PTS treatments. Some are used off-label in selected, severe, or recurrent cases; others are experimental. Discuss risks, costs, and evidence with a specialist.

1. Intravenous Immunoglobulin (IVIG) — see dosing above.
   Function/mechanism: broad immunomodulation that may quiet an autoimmune nerve attack.

2. High-dose corticosteroid pulses (IV methylprednisolone) — see above.
   Function: rapid anti-inflammatory/immunosuppressive effect early in severe presentations.

3. Low-Dose Naltrexone (LDN) — 1.5–4.5 mg nightly.
   Function: immuno-neuromodulation via microglial pathways; still investigational.

4. Methylcobalamin injections — e.g., 1000 μg IM weekly to monthly when deficient.
   Function: neurotrophic support for remyelination and axonal repair.

5. Platelet-Rich Plasma (PRP) perineural injection (investigational)
   Function: growth factor–rich autologous plasma may support local healing; evidence in PTS is limited.

6. Mesenchymal stem cell therapies (experimental, clinical trials only)
   Function: proposed anti-inflammatory and regenerative effects; not established for PTS outside research settings.

Surgeries

1. Microneurolysis of hourglass constrictions
   Procedure: surgeon releases the tight outer layer and adhesions around a focally constricted nerve segment seen on imaging.
   Why: to restore axonal flow and allow recovery when a discrete constriction matches symptoms and recovery has stalled.

2. Nerve grafting
   Procedure: damaged segment is removed and bridged with a graft (often sural nerve).
   Why: for segmental nerve loss that cannot recover across a gap.

3. Nerve transfer
   Procedure: a nearby expendable donor nerve or fascicle is rerouted to the paralyzed target muscle nerve (e.g., spinal accessory→suprascapular, radial→axillary in suitable cases).
   Why: to reinnervate key muscles when original nerve recovery is unlikely or too slow.

4. Tendon transfer
   Procedure: move a functioning tendon (e.g., pectoralis major transfer) to substitute for a paralyzed muscle to stabilize the scapula.
   Why: improve shoulder mechanics and reduce winging in chronic serratus anterior palsy.

5. Scapulothoracic fusion (very rare, last resort)
   Procedure: surgical fixation of the scapula to the ribs.
   Why: for severe, painful winging with failed other options; sacrifices motion for stability.

Prevention tips

1. Keep vaccinations and infections managed with your clinician, but do not avoid needed vaccines; instead, plan heavy upper-body exertion a few days after any shot if you feel sore.

2. Treat respiratory and other infections promptly.

3. Avoid sudden, very heavy overhead work when deconditioned; build strength gradually.

4. Keep good shoulder and scapular conditioning with regular low-load exercises.

5. Set up ergonomic workstations to reduce arm elevation and reach.

6. Prioritize sleep, hydration, and a balanced anti-inflammatory diet.

7. Do not smoke; limit alcohol.

8. Manage diabetes, thyroid issues, and lipids with your clinician.

9. Warm up before sports; cool down and stretch after.

10. Listen to early warning pain — reduce load and switch tasks rather than pushing through sharp shoulder pain.

When to see a doctor (or urgent care)

1. Sudden, severe shoulder/arm pain, especially with later weakness or visible muscle wasting
2. New shoulder blade winging, trouble lifting the arm, or hand drop
3. Shortness of breath, night sweats, fever, or weight loss
4. Neck pain with arm numbness/weakness after trauma (possible cervical spine problem)
5. Worsening weakness after 4–6 weeks, or no functional improvement after 3 months
6. Recurrent episodes, both sides involved, or a strong family history
7. Any concerning medication side effects (rash, swelling, chest pain, black stools, confusion, very high sleepiness)

What to eat and what to avoid

What to eat:

1. Plenty of colorful vegetables and fruits (antioxidants)
2. Omega-3 sources: fish (salmon, sardine), flax, chia, walnuts
3. Lean proteins (eggs, fish, poultry, legumes, dairy or fortified alternatives) to rebuild muscle
4. Whole grains and beans for steady energy
5.  Fermented foods or yogurt for gut health
6. Adequate fluids; consider calcium+vitamin D foods for bone and muscle

What to limit/avoid:

1. Sugary drinks and ultra-processed snacks that can amplify inflammation
2. Trans fats and frequent deep-fried foods
3. Excess alcohol (worsens sleep and neuropathy risk)
4. Very high vitamin B6 supplements
5. Giant single “cheat” meals that disrupt energy and sleep

Frequently asked questions

1. Is PTS the same as a rotator cuff tear?
   No. A tear is a tendon injury seen on shoulder MRI. PTS is a nerve problem with a typical pain-then-weakness sequence and EMG/nerve imaging changes.

2. How long does recovery take?
   Pain usually improves in weeks. Strength can take months; meaningful recovery often appears by 6–12 months, but full recovery may take 2–3 years and can be incomplete.

3. Can it come back?
   Yes, especially in the hereditary form. Many people have only one episode; some have recurrences.

4. Do steroids always help?
   They tend to help pain if started early. Benefit on long-term strength is uncertain. Doctors weigh risks and timing.

5. Will physical therapy make it worse?
   Good therapy helps. It should be gentle early, avoid flares, and progress slowly. Sharp pain means back off and modify.

6. Is surgery common?
   No. Surgery is reserved for clearly proven focal constrictions with stalled recovery or fixed deficits after many months.

7. What tests confirm PTS?
   EMG/NCS after 2–3 weeks can show denervation. High-resolution ultrasound or MR neurography may show swollen or “hourglass” nerves. Diagnosis is mainly clinical.

8. Is PTS contagious?
   No.

9. Should I stop working?
   Not always. Many people work with restrictions. OT can adapt tasks while you heal.

10. Can I exercise?
    Yes — the right kind. Gentle ROM and scapular control first; later, graded strengthening. Avoid heavy, painful overhead work early on.

11. What about supplements?
    Some may help general health or neuropathic pain modestly, especially if you’re deficient. None replace core care or guarantee recovery.

12. Are nerve blocks safe?
    When done by trained clinicians, they can temporarily reduce severe pain. Effects are usually short-lived.

13. Could this be from a vaccine?
    PTS sometimes follows different triggers, including infections or rarely a shot. This is an association, not proof of cause. Do not skip needed vaccines; discuss timing and any prior reactions with your clinician.

14. What if I also feel breathless?
    Seek care urgently. The phrenic nerve can be affected, weakening the diaphragm.

15. What’s the single most important thing I can do?
    Protect sleep, control pain enough to move gently, and follow a steady, graded rehab plan without overdoing it.
