Piriformis syndrome is actually a neuromuscular situation once the piriformis muscle mass (a pear-formed muscle mass within the buttocks) compresses the sciatic nerve (a nerve that extends through the lower spine every one of the way down to the foot). This leads to pain within the buttocks and hips. Injections: https://www.theorthopaedicandpainpractice.com/lower-back-and-buttock-pain/
