Peripheral nerve entrapment occurs when nerves become compressed. The most common symptoms include pain, tingling, numbness, and muscle weakness. Typically, the symptoms affect just one part of the body based on the affected nerve. Typical forms of peripheral nerve entrapment occur with carpal tunnel syndrome (median nerve) and meralgia paresthetica (lateral femoral cutaneous nerve) as a result of repetitive use, compression, or acute injury.
Nerve conduction studies and electromyography are used to diagnose peripheral nerve entrapments. Depending on the affected nerve, various treatments can be considered including physical therapy, minimally invasive interventions, surgical management, and lifestyle modifications. In addition, neuropathic pain medications can assist in managing symptoms.
If pain persists after an extended recovery period following appropriate treatment, neuromodulation techniques including spinal cord stimulation and peripheral nerve stimulation can be employed to modulate the pain.
