What is piriformis syndrome?

The sciatic nerve is just beneath the piriformis muscle. The sciatic nerve can be compressed/irritated by the piriformis muscle. In turn, this can cause pain, tingling, numbness and pins and needles along the back of the leg and in to the foot.

So the piriformis muscle can cause pins and needles in your legs. But where is this muscle?

The piriformis muscle is located in the buttock region, deep to the gluteus maximus muscle (big bum muscle). It runs in a diagonal direction. It is attached to both the front of your sacrum (at the bottom of the spine and the upper portion of the thigh bone. Therefore it plays an important role in hip movement. Specifically, turning the leg and foot outwards.
