Arm Nerve Injuries: Causes, Symptoms, and Treatment
Arm nerve injuries involve damage to one of the major nerves that control sensation and movement in the arm, wrist, or hand. These nerves include the radial nerve, median nerve, and ulnar nerve. Injuries can result from trauma, overuse, pressure, or stretching of the nerve, and may occur anywhere along the arm from the shoulder to the wrist.
Symptoms vary depending on which nerve is affected but may include numbness, tingling, burning pain, weakness, or difficulty moving the hand or fingers. For example, radial nerve injuries can lead to wrist drop, median nerve injuries may cause problems with thumb movement or grip, and ulnar nerve injuries often affect sensation in the ring and little fingers.
Diagnosis is based on a physical exam, neurological testing, and sometimes imaging or nerve conduction studies to assess the extent and location of the injury. Early evaluation is important to prevent long-term loss of function.
Treatment depends on the cause and severity of the injury. Mild nerve injuries may improve with rest, splinting, and physical therapy. More serious injuries, such as those caused by deep cuts or fractures, may require surgical repair or nerve decompression.
