Reflex sympathetic dystrophy also called Complex Regional Pain Syndrome (CRPS) is a chronic pain condition. The key symptom of CRPS is continuous, intense pain out of proportion to the severity of the injury, which gets worse rather than better over time. CRPS most often affects one of the arms, legs, hands, or feet. Often the pain spreads to include the entire arm or leg. Typical features include dramatic changes in the color and temperature of the skin over the affected limb or body part, accompanied by intense burning pain, skin sensitivity, sweating, and swelling. Doctors aren’t sure what causes CRPS. In some cases the sympathetic nervous system plays an important role in sustaining the pain. Another theory is that CRPS is caused by a triggering of the immune response, which leads to the characteristic inflammatory symptoms of redness, warmth, and swelling in the affected area. Because there is no cure for CRPS, treatment is aimed at relieving painful symptoms. The prognosis for CRPS varies from person to person. Spontaneous remission from symptoms occurs in certain individuals. Others can have unremitting pain and crippling, irreversible changes in spite of treatment.[rx]
Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that mainly affects the arms, legs, hands, and feet, but may involve the entire body. CRPS symptoms often begin after surgery or an injury.[1] The main feature of CRPS is continuous, intense pain that is out of proportion to the severity of the injury. The pain gets worse over time and often spreads throughout the entire affected area.[2] Other symptoms may include color and temperature changes of the skin over the affected area; skin sensitivity; sweating; and swelling.[1] The underlying cause of CRPS is often not known. Two classifications of CRPS have been recognized based on causalgia. Type I (also known as reflex sympathetic dystrophy), in which there is no evidence of peripheral nerve injury and Type II, in which peripheral nerve injury is present. Treatment aims to relieve pain and often includes different interventions such as topical or oral medications; physical therapy; and/or a sympathetic nerve block.[2][3]
Types of CRPS
CRPS can be divided into two main types:
- CRPS Type 1: This occurs after an injury or trauma that may not necessarily involve nerve damage.
- CRPS Type 2: This is linked to a known nerve injury.
Common Causes of CRPS
While the exact cause of CRPS is still not fully understood, some common triggers include:
- Injuries like fractures or sprains.
- Surgery.
- Nerve damage.
- Infections.
- Immune system dysfunction.
- Genetics.
- Abnormal inflammation.
- Stress and emotional factors.
- Repetitive motion.
- Stroke or heart attack, leading to reduced blood flow.
Recognizing CRPS Symptoms
CRPS can manifest with various symptoms, including:
- Persistent pain, often described as burning or shooting.
- Swelling in the affected area.
- Changes in skin color and temperature.
- Abnormal sweating patterns.
- Sensitivity to touch.
- Muscle weakness and spasms.
- Joint stiffness.
- Limited range of motion.
- Nail and hair changes.
- Emotional distress, anxiety, and depression.
Diagnostic Tests for CRPS
Doctors may use several tests to diagnose CRPS, such as:
- Clinical examination and medical history.
- X-rays and bone scans.
- MRI or CT scans.
- Nerve conduction studies.
- Sympathetic nervous system tests.
- Thermography.
- Sweat tests.
- Blood tests to rule out other conditions.
- Diagnostic nerve blocks.
Available CRPS Treatments
CRPS treatment aims to relieve pain and improve function. Common treatments include:
- Physical therapy to improve mobility and strength.
- Occupational therapy to assist with daily tasks.
- Medications like nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation.
- Nerve pain medications like gabapentin and pregabalin.
- Topical analgesics for localized pain relief.
- Sympathetic nerve blocks to alleviate pain.
- Spinal cord stimulation to modulate pain signals.
- Intravenous ketamine infusions for severe cases.
- Graded motor imagery techniques.
- Mirror therapy to retrain the brain’s perception of the affected limb.
Medications for CRPS
Several medications can help manage CRPS symptoms, including:
- Non-prescription pain relievers like acetaminophen.
- Over-the-counter NSAIDs.
- Prescription opioids for severe pain.
- Antidepressants for pain modulation and mood improvement.
- Anticonvulsants for nerve pain.
- Muscle relaxants for muscle spasms.
- Topical lidocaine or capsaicin creams.
- Nerve block injections.
- Corticosteroids for inflammation.
Conclusion
CRPS is a challenging condition to deal with, but understanding its types, causes, symptoms, diagnostic tests, and available treatments can provide valuable insight into managing and coping with this disorder. If you or someone you know is experiencing symptoms of CRPS, it’s essential to seek medical attention promptly. Working closely with healthcare professionals can help improve your quality of life and alleviate the pain associated with CRPS.
By breaking down the complex nature of CRPS into simple language, we hope to increase awareness and accessibility to information about this condition, making it easier for those affected to navigate their journey towards relief and recovery.
