Radiculitis / Radiculopathy
Radiculitis is inflammation or irritation of the root of a spinal nerve. The Latin word radix means root. Radiculopathy is radiculitis caused by the nerve root being compressed by a compressed vertebral disk or arthritis. Radiculitis is characterized by pain that seems to radiate from the spine to extend outward to cause symptoms away from the source of the spinal nerve root irritation. The term radiculitis is used when symptoms demonstrate nerve root irritation but x-rays and other radiology show no abnormalities.
