Hi All, just joined this forum hoping for some advice from the people in the know! I've had crohns since 2001 and over last couple of years had a bit of a rough time. Anyway had surgery for the 4th time back in March this year and felt really well for a while....sadly recent colonoscopy confirmed what I had feared the dreaded crohns was back. GI wants to try 6MP to start in January to try to get control of the flare up, my only concern is that i've heard it is similar to Azathioprine which I could not tolerate:thumbdown: Can anyone help with what to expect? There seems to a lot of mention of ulcers??? Just wondered what type of ulcers and also sickness etc. I would really appreciate some input. Thanks Guys x
