Question:
What is bi lateral piriformis?
Answers:
bi-lateral means right AND left
Piriformis is a muscle (probably named for it shape) that (when one side flexes) hikes your (that side) hip. It is very tender after injury, e.g. from pelvic whiplash from auto injury, and must be treated (medically massaged) if not torn, to be okay again.
When both sides are flexed simultaneously the hips are then stablized for other muscular contractions to work specific functions
