This is my first post. I’ve had rectal pain non stop for seven years. It started after having a BCIR surgery. That is an internal bag for waste made out of small intestine so it can be emptied using a catheter. My rectum was removed forty years ago due to ulcerative colitis. I had illiosmy for two years then a Koch Pouch which is similar to the BCIR. It lasted for many years until 2000 with the valve failed and started leaking. The rectal pain is unrelenting and feels like a hot jagged post twisting and poking into my backside. I’ve tried everything from a hysterectomy to a spinal laminectomy to every kind of injections you can think of. I’ve recently received a DRG Stimulator that goes under the tailbone. It is the first thing to give any marked relief but the pain is still such that my life is very restricted. Has anyone ever heard of a intrathecal pump for pain in this area?
