The term radiculopathy refers to describe pain, and other symptoms like numbness, tingling, and weakness in your arms or legs caused by a irritation or compression of nerve roots.
This term comes from a combination of the Latin word “radix,” which means the roots of a tree, and “pathos,” which means a disease.
This condition is often caused by direct pressure from a herniated disc or degenerative changes in the lumbar spine that cause irritation and inflammation of the nerve roots.
Pain and numbness is felt in the area of skin supplied the by sensory fibers of the nerve root. In addition the muscles supplied can show weakness.
Radiculopathy pertaining to lower limb is commonly referred to as sciatica.
