Radiculopathy is a pinched nerve in the spine. It occurs when surrounding bones, cartilage, muscle, or tendons deteriorate or are injured. The trauma causes these tissues to change position so that they exert extra pressure on the nerve roots in the spinal cord.
Symptoms of radiculopathy can range from mild to severe. The type and location of pain depends on the location of the pinched nerve root. Cervical radiculopathy usually affects the lower arm more than the neck area. Lumbar radiculopathy causes more discomfort in the lower leg than in the back area.
When the nerve roots are compressed, they become inflamed. This results in numbness, weakness, and pain. The condition can usually be reversed with timely and appropriate treatment.
