I really think you should get a second opinion (that's my opinion) My boyfriend was just diagnosed with this and his gastro told him to just eat anything... we are being careful what he eats and definitely avoiding NSAIDS as they exasperate his problem..he got a medication from the doctor to take with an NSAID if he has to take one for his back pain and he does watch what he eats..his was diagnosed with a CT scan!! Prayers for you to get some answers!!
