Hi all! I'm going to the Mayo Clinic tomorrow. My Crohn's has only appeared in my ascending Colon, but I get internal bleeds to the point of hospitalization and blood transfusions. The latest visit, I had 2 Colonoscopies, and I saw the images. My Crohn's was very minimal-not enough to show how I could be losing so much blood. My appointment tomorrow is with the Gynecologist to see if possibly I have Endometriosis attacking my colon from the outside! If so, I will have surgery to remove it. I pray that is what it is, since my Crohn's doesn't normally bother me, but has been painful and unusually active since July 2013. I'm not on any medications (Thank GOD I got off Pred 2 days ago). I'm wondering if that might be included in this list?
