Treatment of Meralgia Paresthetica When Conservative Management Has Not Resolved Symptoms
Meralgia paresthetica presents with lateral thigh pain and paraesthesia caused by entrapment of the lateral femoral cutaneous nerve. When a course of conservative management does not achieve symptom resolution, a structured next-line treatment approach is indicated.
Prior Treatment — Insufficient Response
Conservative management — comprising removal of restricting clothing, local ice application, a short course of NSAIDs, and avoidance of exacerbating physical activities — is the standard first step. This protocol applies when those measures have failed to resolve the lateral thigh pain and paraesthesia.
Next-Line Approach
When conservative care has not been sufficient, the next step involves a targeted, image-guided perineural injection at the lateral femoral cutaneous nerve combining a corticosteroid with a local anaesthetic. The complete regimen — including agent selection, specific volumes, and procedural technique — is available in the full protocol.
Treatment Goal
Complete resolution of meralgia paresthetica symptoms at 2 months.

- Klauser et al. [22] performed injections in 20 patients (9 male, 11 female) using a 27G needle with a mixture of 1 ml triamcinolone acetonide (10 mg/ml), and 5 ml of 0.5% bupivacaine.
- The injection regime was 1 ml of betamethasone disodium phosphate (5 mg/mL) and 2 mL of prilocaine (2%) using a 22G needle.
- Kloosterziel et al. designed a 20-patient double-blind randomised, placebo-controlled trial which compared the injection of 2 mL methylprednisolone/lidocaine (80 mg methylprednisolone, 20 mg lidocaine) with 2 mL saline 0.9%.
- The remaining 4 patients had a further injection and all 20 patients reported complete resolution of symptoms at 2 months.
