If a disc becomes injured or degenerates, it can tear, allowing the soft jelly-like center to bulge out and press on an adjacent nerve. Heavy lifting, obesity and contact sports can contribute to the problem. Your doctor may test your strength, sensation and reflexes and look for problems of restricted movement. An EMG test may be performed to determine the nerve conduction speed in your arms and legs. Your doctor may advise adjustment or cessation of an activity that is causing pressure on a nerve and may suggest wearing a splint, brace or some other support.
Physical therapy can strengthen surrounding muscles.
Anti-inflammatory drugs or a short course of corticosteroids can promote healing. Small doses of amitriptyline or another tricyclic antidepressant, sometimes prescribed for pain, may help if your case is chronic. Prevention Try to avoid tasks that involve repetitive hand, wrist, arm or shoulder motions. When avoidance is impossible, perform the motions for short periods of time with breaks in between. If symptoms begin to appear, consult a physical therapist to learn about possible modifications in the task or the equipment.
