- The condition known as sciatica is caused by compression or irritation of the sciatic nerve where it joins to the spinal cord in the lumbar region of the spine. The sciatic nerve is the longest in the body, traveling from the lower back, through the buttocks, behind the thigh and down the leg to the feet and toes.

Where is the sciatic nerve located in the body? Sciatica is a form of nerve dysfunction that can occur when the sciatic nerve is compressed. Often, the source of the pressure is a degenerative spine condition, such as a herniated disc or bone spur, which causes narrowing of nerve passages and compresses the sciatic nerve. The resulting symptoms, known as sciatica, arise when motor or sensory impulses are unable to pass properly along the length of the nerve. Sciatica can include: Pain

Piriformis Syndrome Piriformis Syndrome. Piriformis trigger points, by keeping the muscles tight and rock hard, can cause actual sciatic nerve compression. Pain from piriformis trigger points is harsher and more electric than pain from gluteus minimus trigger points and is felt in the back of the thigh, the calf, and the sole of the foot. There may also be other abnormal sensations, such as numbness, tingling, burning, or hypersensitivity, in any of these areas.

- From Wikipedia, the free encyclopedia. Piriformis syndrome is a neuromuscular disorder that occurs when the sciatic nerve is compressed or otherwise irritated by the piriformis muscle causing pain, tingling and numbness in the buttocks and along the path of the sciatic nerve descending the lower thigh and into the leg.owever, compression may be present, but not causal, in the setting of sciatica due to piriformis syndrome. The syndrome may be due to anatomical variations in the muscle-nerve relationship, or from overuse or strain.

Sciatica Sciatica causes pain that begins in the lower back and spreads through the buttock, leg, calf and, occasionally, the foot. The pain generally will feel dull, aching or burning.

Sciatica In some cases, the center can spread out and press against a sciatic nerve, causing sciatica. Arthritis in the back may cause extra bone to grow along the spine and is another possible cause of sciatica. So, more rarely, is a sprained ligament in the back, which swells up and presses against the sciatic nerve.

Sciatica Causes 6 most common causes of sciatica. There are 6 lower back problems that are the most common causes of sciatica: Lumbar herniated disc. A herniated disc occurs when the soft inner core of the disc (nucleus pulposus) leaks out, or herniates, through the fibrous outer core (annulus) and irritates the contiguous nerve root.

- Sciatica is the name given to any pain stemming from the irritation of the sciatic nerve. Anything that irritates this nerve can cause pain that ranges from mild to severe; usually, from a compressed nerve root in the lumbar (lower) spine.he main symptom of sciatica is a shooting pain anywhere along the sciatic nerve; from the lower back, through the buttock, and down the back of either leg (usually only one leg is affected). This pain can range from mild soreness to a sharp pain or severe discomfort, and may be aggravated if you sit for long periods.

Sciatica 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 another medical problem. It is not a medical condition on its own. 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:
