sciatica (redirected from Lumbar radiculitis)

sciatica (sīăt`ĭkə), severe pain in the leg along the sciatic nerve and its branches. It may be caused by injury or pressure to the base of the nerve in the lower back, or by metabolic, toxic, or infectious disease. Treatment is for the underlying condition; measures for the relief of pain include bed rest, immobilization of the leg, heat, and sedation.

sciatica

Pain along the course of the sciatic nerve, from the lower back down each leg. It often begins after lower back strain and is associated with spinal disk herniation. Pain is increased by coughing, sneezing, or bending the neck forward. Muscle relaxants, painkillers, and nerve stimulation are among the treatments, but surgery to relieve pressure on the nerve is needed if pain is disabling or nerve function is progressively disturbed (with leg weakness and loss of feeling). Rarely, sciatica arises from other causes of nerve compression (e.g., tumour) or disorders involving the peripheral nervous system.
