Hi, is there another way to detect IBD other than a colonoscopy and endoscopy? I have had both and was instead diagnosed with IBS but my symptoms are so severe (rectal bleeding (bright red), flare ups - can go months with nothing and then comes back out of no where, terrible back pain, the flare ups are so bad that I sometimes vomit from the stomach pains). I am worried and want to make sure I have done all tests possible to ensure it is just IBS, everytime i speak to a doctor they tell me its anxiety related.
