i have had stomach problems since I was 8. I am now 37. I have seen many Doctors and was told I had IBS and then told Crohns. I have had more than 10 i&d's for perianal abscesses. The newest GI i am seeing has told me I have IBS. He has not ran any tests. Had me do cipro/flagyl combo. Didnt work. Then got me on xifaxan. Didnt work. 

Last week i developed a bad cold and saw the nurse practitioner. She gave me a prednisone shot and a weeks worth of prednisone tabs. All stomach issues have been resolved since starting the prednisone. No more pain, cramps running for the bathroom etc. 

Is it possible I have had Crohns and it has been missed since I have had no definitive diagnosis? I just found it odd that all the IBS treatments havent worked but the steroid did.
