When my son had bad flare ups, it was in his colon, there were no mention of his small intestines being flared up. I’m pretty sure that they told me that besides swallowing the camera, that my eliem, which connects your small to your large intestines was without any ulcers and that this was also a determination that I didn’t have Crohn’s. I’m not a doctor but, I was just speculating that your husband may have had Crohn’s disease and that possibly he’s been in remission since his surgery. A little far fetched wouldn’t you think but, always something to think and ask about with his surgeon!.. my son was so ready to give up at one time because he was so malnourished and the pain, the pooping, not going out in fear of an episode, he decided that he was no longer going to take his remicade, (one of few treatments), any longer and started smoking marijuana, well guess what?... he’s been in remission for like 12/15 years now and looks great! So what I’m saying is, is that everyone is different, I’m still struggling with my jpouch , just trying to figure out the right combination!.. nice hearing from you, and again, prayers for your husband that he gets well soon..
