Hi Justin: My dr. said it would take 24-48 h. before I would feel any difference. I haven’t felt much better. I am scheduled for another shot next week. Since I had problems with the piriformis muscle before I wanted to have a shot in that area before I had an epidural. That would be my last resort. I also want to start PT. Am interested in ART (active release therapy) which I heard can be very beneficial. I have absolutely no pain upon sitting but feel severe muscle cramping in my groin and lateral thigh upon standing. Was wondering if anyone else had the same problems. Am just not sure if this is from bulging discs or spinal stenosis.
