I had piriformis surgery 5 months ago i still have severe sciatic pain , the surgeon removed the whole body of the muscle, i just started phys therapy?

See below: Not sure i can encourage you, as my experience with surgery to relieve piriformis syndrome problems has always been disappointing. Would get an opinion from an experienced osteopath, who works with sacro-iliac problems as omt is better suited to help you rehabilitate. Would also consider updated EMG to check status of sciatic nerve.
