With a pinched nerve in the lower back, pain is usually felt radiating down the leg. This pain travels the length of the nerve. With a pinched nerve in the neck, pain is usually felt radiating down the arm.
Painful muscle spasms in the back often occur with pinched nerves. Sometimes, the only symptoms may be numbness and weakness in an arm or leg without any pain.
Causes and Risk Factors
Radiculopathy or a pinched nerve usually occurs when a nerve is squeezed (compressed) by the intervertebral disc, a bone spur, or by the vertebra slipping, which causes narrowing. Non-spine causes can be by overuse. Overuse, as in carpal tunnel syndrome, can cause a pinched nerve.
