I had my reversal about 7 weeks ago. I am very happy with it - but I had UC, not Crohn's. The X rays before the surery were no big deal for me. No pain, and it was easy to hold in the contrast dye. I got up and went to the bathroom to expell it normally after the x rays. I had a very easy time recovering from reversal surgery, no incontinence, no urgency, and no butt burn or excessive gas. I am surprised your doctor would tell you such short recovery times, however. I am still not having very formed stools. I am told it can take up to a year for things to get completely healed. Also, I go more than 3 or 4 times a day, and I think that it is very common to go 10-20 times a day right after surgery. I don't mind at all, though, because I can hold it fine, and have no pain.
Feel free to ask any questions you have!
