With a pinched nerve in the lower back, pain is usually felt radiating down the leg. This pain travels the length of the nerve.
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
A pinched nerve usually occurs when a nerve is squeezed (compressed) by a ligament or tendon, or between a bone and a ligament or tendon. Various spinal conditions, such as a herniated disc or arthritis, can create rough spots in the bone through which a nerve root passes. Overuse, as in carpal tunnel syndrome, can cause a pinched nerve.
