(Latin: "little root"; pertaining to nerve roots)
2. Simultaneous inflammation of a large number of the spinal nerves marked by paralysis, pain, and the wasting away of muscles.
2. A type of pain felt in the extremities (most commonly the arms or legs) along the course of spinal nerve roots.
Inflammation or compression of the spinal nerve from conditions; such as, stenosis or a herniated disc can trigger radicular pain.
If a cervical condition is causing radiculopathy; for example, cervical stenosis, it can cause arm, neck, and shoulder pain.
If a lumbar condition is the cause; that is, a lumbar herniated disc, it can cause leg pain and sciatica or pain that results from irritation of the sciatic nerve which is the largest nerve in the body that begins in the lumbar spinal cord in the lower back (sacrum) and extends through the buttocks area, sending nerve endings down through the legs and knees.
