Sciatica refers to pain, weakness, numbness, or tingling in the leg. It is caused by injury to or pressure on the sciatic nerve. Sciatica is a symptom of a medical problem. It is not a medical condition on its own.
Neuropathy - sciatic nerve; Sciatic nerve dysfunction; Low back pain - sciatica; LBP - sciatica; Lumbar radiculopathy - sciatica
Sciatica occurs when there is pressure or damage to the sciatic nerve. This nerve starts in the lower back and runs down the back of each leg. This nerve controls the muscles of the back of the knee and lower leg. It also provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot.
Common causes of sciatica include:
- Slipped disk
- Spinal stenosis
- Piriformis syndrome (a pain disorder involving the narrow muscle in the buttocks)
- Pelvic injury or fracture
Men between 30 and 50 years of age are more likely to have sciatica.
