What is piriformis syndrome?
The piriformis is a small muscle deep in your buttock. The sciatic nerve runs right past it — and
in some people, straight through it. When that muscle stays tight and irritable, it can compress or
irritate the nerve and produce pain that behaves exactly like sciatica: deep in the buttock, worse
sitting, running down the back of the leg.
What actually causes it
Almost never the piriformis by itself. Muscles that small do not become bullies for no reason. They
tighten because they are covering for something — a pelvis that is not level, a hip that has stopped
doing its share, years of sitting, months of guarding after a flare-up. Attack the piriformis alone
and you are punishing the employee, not the manager.
Why digging into it backfires
Ball under the glute, elbow from a massage therapist, aggressive figure-4 stretching — short relief
followed by a worse night, over and over. It is already overworked. More pressure means more guarding.
What works instead
- Work the non-painful side first to take load off the irritated side.
- Get the pelvis level and both hips sharing the work — balance, then stabilize.
- Then return to normal activity, so the muscle has no reason to go back on duty.
