What is radiculopathy/nerve impingement?

Radiculopathy refers to a condition in which the spinal nerve roots are irritated or compressed. Many people refer to it as having a “pinched nerve.”

Lumbar nerve impingement indicates that the nerve roots in the lower spine are involved, while cervical radiculopathy is associated with nerve roots in the neck. Nerve impingement is most often caused by a herniated disc or spinal stenosis.
