Piriformis syndrome is a rare disorder of the nerves and muscles. It occurs when the piriformis muscle, located in the buttocks, spasms and presses on the sciatic nerve, causing pain and numbness in the buttocks and down the back of the leg. The syndrome is uncommon, but it can cause sciatica-type symptoms.

What You'll Learn
Piriformis syndrome is a rare disorder of the nerves and muscles
The syndrome is uncommon, but it affects more women than men. It can cause sciatica-type symptoms, including pain, numbness, and tingling along the back of the thigh and leg. Research suggests that up to 17% of patients with chronic low back pain and leg pain may have piriformis syndrome.
The piriformis muscle is located deep in the buttock, and it runs diagonally, with the sciatic nerve running vertically directly beneath it. However, in some people, the nerve can run through the muscle. Patients with piriformis syndrome typically describe symptoms of acute tenderness in the buttock and sciatica-like pain down the back of the thigh, calf, and foot.
Part of the diagnosis process for piriformis syndrome is ruling out other possible disorders that can mimic its symptoms, such as sacroiliac joint dysfunction or lumbar disc disease. This is because the treatment for piriformis syndrome may differ from the treatment for sciatica, which is caused by a variety of lower back conditions.

The piriformis muscle is located in the buttock region
Piriformis syndrome is a rare disorder of the nerves and muscles. It occurs when the piriformis muscle in the buttocks presses on the sciatic nerve, which runs from the lower spine down the back of the leg to the foot. This can cause pain and numbness in the buttocks and down the back of the leg. It can also cause sciatica-type symptoms, such as pain, numbness and tingling along the back of the thigh and leg.
The syndrome is uncommon, but it affects more women than men. Injuring or irritating the piriformis muscle can cause muscle spasms. Research suggests that up to 17% of patients with chronic low back pain and leg pain have piriformis syndrome. Part of the diagnosis process for piriformis syndrome is ruling out other possible disorders that can mimic its symptoms, including sacroiliac joint dysfunction or lumbar disc disease.
Treatment for piriformis syndrome may differ from treatment for sciatica, which is caused by a variety of lower back conditions.

The syndrome causes pain and numbness in the buttocks and down the back of the leg
Piriformis syndrome is a rare disorder of the nerves and muscles. The piriformis muscle is located in the buttock region and is involved in nearly every movement of the lower body, from walking to shifting weight from one foot to the other. When the piriformis muscle spasms, it can cause buttock pain and irritate the nearby sciatic nerve, which runs from the lower spine down the back of the leg to the foot. This can result in pain, numbness, and tingling along the back of the thigh and leg, similar to sciatica. Symptoms may include acute tenderness in the buttock and sciatica-like pain down the back of the thigh, calf, and foot.
Piriformis syndrome is characterised by pain and numbness in the buttocks and down the back of the leg. The syndrome occurs when the piriformis muscle in the buttocks presses on the sciatic nerve. This nerve runs vertically beneath the piriformis muscle, which runs diagonally. In some people, the nerve can run through the muscle. The piriformis muscle is important for lower body movement, stabilising the hip joint and lifting and rotating the thigh away from the body.
The syndrome can cause sciatica-type symptoms, including pain, numbness, and tingling along the back of the leg. It is more common in women than in men, although it is uncommon overall. Injuring or irritating the piriformis muscle can lead to muscle spasms, which can further aggravate the nearby sciatic nerve root. This can result in sciatica-like symptoms racing down the large sciatic nerve.
The diagnosis process for piriformis syndrome involves ruling out other possible disorders that can mimic its symptoms, such as sacroiliac joint dysfunction or lumbar disc disease. This distinction is important because treatments may differ for piriformis syndrome compared to sciatica, which is caused by a variety of lower back conditions.

The piriformis muscle can irritate the sciatic nerve
Piriformis syndrome is a rare disorder of the nerves and muscles. The piriformis muscle is a flat, band-like muscle located in the buttocks, near the top of the hip joint. It is important for lower body movement, stabilising the hip joint and lifting and rotating the thigh away from the body. This is how we are able to walk, shift our weight from one foot to another, and maintain balance. The piriformis muscle can also irritate the nearby sciatic nerve. This nerve runs from the lower spine down the back of the leg to the foot. When the piriformis muscle goes into spasm, it can cause pain, numbness and tingling along the back of the thigh and leg, similar to sciatica. Symptoms include acute tenderness in the buttock and sciatica-like pain down the back of the thigh, calf and foot.
The piriformis muscle is involved in nearly every movement we make with our lower body, from walking to shifting weight from one foot to the other. When the piriformis muscle is injured or irritated, it can cause muscle spasms. This can then irritate the sciatic nerve, causing pain, numbness and tingling.
Piriformis syndrome is more common in women than men, and it is thought that up to 17% of patients with chronic low back pain and leg pain have the condition. It is important to distinguish piriformis syndrome from sciatica, as the treatments may differ. Sciatica is caused by a variety of lower back conditions, whereas piriformis syndrome is caused by a problem with the piriformis muscle itself.
