Disc bulge causing a pinched nerve.
Nerve compression can occur in many locations throughout your body. Typical sites include your lower spine (lumbar region) and neck (cervical region). A pinched nerve in the back often results in sciatica, pain that is felt in your buttocks and radiates down to the back of your upper leg are rarely below the knee. A pinched nerve in the neck may cause radiating pain, numbness, tingling, and weakness felt in the arms and hand. Nerve compression is not restrained to spinal nerve roots alone. For example, a pinched nerve in your wrist can lead to carpal tunnel syndrome, pain and numbness in your hand and fingers.
Note From Dr. Liu
With rest and other conservative treatments, most people recover from a pinched nerve in the neck or back within a few days or weeks. Sometimes, however, surgery is necessary to relieve pain.
Generally, there is no need to be worried about symptoms that are around for only a short time. If a nerve is compressed for only a short duration, it generally doesn’t cause permanent damage. And once the pressure is relieved, normal nerve functions are restored. However, if the symptoms stay for a long time and the pinched nerve is not relieved, much more serious symptoms such as chronic pain, nerve death, or muscle atrophy could occur.
