Meralgia paresthetica is a condition that causes pain, numbness, and tingling in the outer part of the thigh. Here are the key points about this condition:
Symptoms
The main symptoms of meralgia paresthetica include:
- Tingling, burning pain in the outer thigh
- Numbness or decreased sensation in the affected area
- Hypersensitivity to touch in the thigh
- Pain that may worsen after walking or standing
These symptoms typically occur on only one side of the body.
Causes
Meralgia paresthetica is caused by compression of the lateral femoral cutaneous nerve, which provides sensation to the outer thigh. Common causes include:
- Tight clothing like belts or pants
- Obesity or weight gain
- Pregnancy
- Diabetes
- Trauma or injury to the nerve
- Scar tissue from previous surgery
Diagnosis and Treatment
Diagnosis is usually based on symptoms and physical examination. Treatment options include:
- Conservative measures like wearing looser clothing and weight loss
- Soft tissue therapy such as active release techniques
- Stretches and strengthening
- activity modification
Most cases resolve with conservative treatment. Surgery is only considered if symptoms persist after several months of non-surgical management.
Prognosis
Meralgia paresthetica is often self-limiting, with about 62% of untreated patients experiencing complete symptom resolution within 2 years. However, some cases may become chronic if left untreated. Early diagnosis and appropriate management can help prevent long-term disability.
