So, I've been getting this new pain, new to me anyway. I've heard others describe it here before. It feels like someone is stabbing me with a hot needle, a BIG needle. I keep getting this right in the area where caudal injections are done and also a little lower on both sides of my bum. I've had this before once in a while but lately its been frequent. I was wondering if because of the location is it SI related or if it has to do with my disc herniations. Any one else had this pain in this location?
