Nerve root compression, also known as radiculopathy or a "pinched nerve, " occurs when a nerve root in the spine is compressed or irritated, often causing pain, numbness, or weakness in the area supplied by that nerve. Most commonly affects the lumbar and cervical spine. What it is: Nerve Root Compression: This refers to the condition where the nerve roots, which branch out from the spinal cord, are compressed or irritated.  Radiculopathy: This is a medical term for nerve root compression or irritation.  Pinched Nerve: This is a common term used to describe nerve root compression. Causes: Herniated Disc: A bulging or ruptured disc can press on a nerve root. Spinal Stenosis: Narrowing of the spinal canal can put pressure on the nerve roots. Osteoarthritis: Bone spurs and other changes in the spine can irritate nerve roots. Tumors or Abscesses: In rare cases, tumors or infections can compress nerve roots.
