I agree with Mormor Vicky
If you dont feel well then your doctor needs to find something that will help. A GI should be be able to help you with the issues even if its not Crohn's related.
Finding a good doctor is really difficult but it may be worth trying to talk to your GI again about your pain and see if he can suggest something to help, if not then you need to find someone who will.
Good luck!
