I have had the same problems since the day after my takedown 6 months ago. I am going through the same pains you are describing, I have tried everything from eliminating dairy, gluten, & extra sugar, with no results. I have tried Beano, Gas-X and they seem to make things worse, I also avoid carbonated beverages. I am not on medication and am convinced the pains are from UC/Chron's. The biggest relief I have found so far is laying on my stomach and releasing gas, use caution however. Can anyone else give input? I am stuck in the same boat and it is miserable. I do have a small pin-hole sized leak that is healing and being watched, that's the only explanation I have been given related to these pains so far.
