A pinched nerve can occur at several sites in your body. A herniated disk in your lower spine, for example, may put pressure on a nerve root, causing pain that radiates down the back of your leg. Likewise, a pinched nerve in your wrist can lead to pain and numbness in your hand and fingers (carpal tunnel syndrome).
Nerves extend from your brain and spinal cord, sending important messages throughout your body. If you have a pinched nerve (nerve compression) your body may send you warning signals such as pain. Don't ignore these warning signals.
Damage from a pinched nerve may be minor or severe. It may cause temporary or long-lasting problems. The earlier you get a diagnosis and treatment for nerve compression, the more quickly you'll find relief.
In some cases, you can't reverse the damage from a pinched nerve. But treatment usually relieves pain and other symptoms.
