Thanks for the help interpreting the results, I'm very relieved that it's probably not Crohn's because I really don't think I could cope with that on top of the problems I'm having now.
The inflammation could be a drug side effect, I never touch NSAIDs but with the large amount of pills Im taking I wouldn't be surprised if it was causing problems elsewhere.
I think I will ask to be referred to another hospital for a second opinion, I've seen about
5 different GIs at the current one (otherwise appointments are months apart) and they're all pretty much the same. I'm allowed a second opinion on the NHS, maybe I should try and find a doctor with experience in abnormal cases like mine.
This is all really getting too much for me
