Welcome to the Chronic Pain forum littleorange!
Sorry you are struggling with this type of pain! Did you ask you're Dr what options you had, if any? I realize he said you may always have this pain, but did he offer a solution for you?
If nothing can be done, then I would think pain med's of some sort would be the only solution. It would be a hassle, but maybe a numbing cream of some type?
Many of us have had surgeries, and wind up with some sort of painful scar tissue. I experience this from my own lumbar surgery, and is in the groin area. (not fun)...Taking pain med's for my FBS (Failed Back Surgery) helps with this.
Hopefully someone else can suggest a better direction for you. You might want to check out the "Ostomies" forum, and visit with those members over there. I'm willing to bet they deal with this sort of problem as well.
Good luck, and do visit us often!
