People with piriformis syndrome typically suffer from low-back pain. Dr. Nelson notes that patients may also experience shooting pain and numbness in the buttocks, thighs or legs.
Exactly where is the piriformis?
The piriformis muscle extends along both sides of the lower buttocks. This small muscle attaches to the front of the middle pelvic bone (sacrum), passes through a hole in the pelvic bone (greater sciatic foramen) and connects to the top of the thigh bone (femur).
What is Piriformis Syndrome?
Sciatic nerves travel beneath the piriformis muscle- much like a highway underpass- on their way from the spine to the back of each leg.
Dr. Nelson describes to patients that piriformis syndrome occurs when the muscle becomes inflamed, forcing pressure on the sciatic nerve and entrapping it against the bones of the pelvis.
Along with compression of the sciatic nerve, the piriformis muscle itself is often tender and painful. Posture is also affected, with the pelvis bones (sacrum and iliac bones) moving slightly out of place. This misalignment is known as a sacroiliac subluxation.
The spinal bones of the lower back, known as the lumbar vertebrae, also tend to move slightly out of place - a condition termed vertebral subluxation.
In addition to aggravating piriformis inflammation, sacroiliac and vertebral subluxation may trigger a vast array of maladies, including back pain, leg pain, headaches, intestinal problems and infertility, explains Dr. Nelson.
