Peripheral nerve entrapment occurs when a nerve is compressed or pinched, often due to surrounding tissues such as muscles, tendons, or ligaments. This condition can lead to symptoms like pain, numbness, tingling, or weakness in the affected area. Common sites for entrapment include the wrist, where it can cause carpal tunnel syndrome, and the elbow, leading to cubital tunnel syndrome. Diagnosis typically involves a physical examination and may include imaging tests or nerve conduction studies. Treatment options range from rest and physical therapy to medications and, in some cases, surgery to relieve the pressure on the nerve. Early intervention can help prevent long-term damage.
