Definition Sciatica refers to pain, weakness, numbness, or tingling in the leg. It is caused by injury to or compression of the sciatic nerve. Sciatica is a symptom of another medical problem, not a medical condition on its own. Alternative Names Neuropathy - sciatic nerve; Sciatic nerve dysfunction Causes, incidence, and risk factors Sciatica occurs when there is pressure or damage to the sciatic nerve. This nerve starts in the spine and runs down the back of each leg. This nerve controls the muscles of the back of the knee and lower leg and provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot. Common causes of sciatica include: Piriformis syndrome (a pain disorder involving the narrow piriformis muscle in the buttocks) Slipped disk Degenerative disk disease Spinal stenosis Pelvic injury or fracture Tumors

Highlights Overview: Back pain can be acute, subacute, or chronic, and more commonly occurs in the lower area of the back.
Acute back pain develops suddenly and lasts up to several weeks. Acute pain is the most common type of back pain. Subacute back pain is pain that lasts up to three months. Chronic back pain can begin abruptly or gradually, linger, subside and then come back, but it lasts longer than 3 months. With proper self-care, most acute cases resolve within 4 - 6 weeks. Two-thirds of those patients, however, will experience another episode of back pain within 12 months. Diagnosis: A medical history and a brief physical examination is always necessary for both acute and chronic back pain. The main goal of a physical exam is to try and determine the source of the pain and to detect warning symptoms. Imaging techniques such as x-rays or scans are rarely recommended in the first month unless the health care provider suspects a serious problem such as a tumor, fracture, infection, caud...
