I've had 2 surgeries in the same area. The degenerative issues and stenosis is NOT related to IBD, colectomy, j-pouch, etc. Sounds like degenerative issues, and nerve issues because of that. Cortisone shots are very helpful for some, but they may only last 6-12 months. The neurosurgeon should have or refer you to a pain specialist as well. Degenerative disc disease is simply a matter of age, use, etc. Kinda like a car getting older 😉. Stretching, physical therapy, therapeutic massage and Chiropractic care, and pain medication (non-opiod) have been immensely helpful, and keep me going on a daily basis. However, as I mentioned, I have had 2 surgeries, and the last was an L3/4/5 fusion (with 2 rods and 6 screws). So, do whatever you can to find a way to make life bearable and livable before you need to have surgery.
