Hi, I'm not posting a reply because I have any suggestions about the cause of your pain but to address a potential problem with advice you have already been given. Anti-inflammatories are the single most dangerous, freely available drugs for anyone with stomach or bowel problems. In fact, I have a stoma and no colon as a direct result of their use. I had proctitis, a localized form of ulcerative colitis and took care of it by medication for 20 years until my doctor, against the advice of my gastro specialist, prescribed Naproxen for a joint problem I was suffering. After nine days on them, I could pass nothing but blood and my colon went into spasm and the ulcers spread completely throughout it. I was rushed in and put on high dose IV steroids but to no avail, and I ended up with an emergency ileostomy. I've recently (just over two weeks ago) had an ileo-anal pouch created and, during recovery, my surgeon prescribed diclofenac (Voltarol), (despite my previously having apprised him of the situation). These made me sick and caused me pain after just a few, so I refused to take any more. My specialist was not surprised; surgeons may be good at their job without fully understanding causation as it's not their specialty.
I know that everyone's different, but it is a known fact that this class of drug has more potential problems than the general public (who throw them down their throats like sweeties) are aware.
Before taking or asking for any anti-inflammatories, discuss this with your gastric specialist; otherwise, you could be storing up trouble for yourself. I advise anyone else using them to do the same.
