Nerve injuries in the arm should be treated with general therapy, medication, physical therapy, and surgery depending on the cause. Common causes include trauma, vascular syndrome, cervical spondylosis and so on. 1. Trauma: pulling injury caused by external factors, such as cutting injury, sharp instrument injury, fracture and so on. Nerve injury caused by trauma should be given surgical treatment to repair the nerve as soon as possible, so as not to affect the later functional recovery. 2. Elbow tube syndrome: manifested as numbness, pain and other symptoms of the hand. Conservative treatment can be adopted for those who have a short course of disease, mild and only have abnormal sensation, hand weakness and poor dexterity. If the conservative treatment is ineffective or there is a decrease in hand strength and muscle atrophy, surgery should be taken in time. 3. Cervical spondylosis: Physical therapy such as massage, acupressure, traction, etc. can be used to relieve the symptoms of mild symptoms, and non-steroidal anti-inflammatory and analgesic drugs such as ibuprofen and aspirin can be taken to relieve the pain. When symptoms are severe, immediate medical attention should be sought, and if necessary, surgical treatment is feasible.
