I was kidding about the impatience... I'm the SAME way. But it's true. :)
OK, the thing in my view and experience is that if you don't look at it as co-morbidity (for those who don't understand what co-morbidity is: think of it as having more than one thing that sucks at one time), just think of it as having some sort of problem in your body that affects a few things. At least for me it is not so frustrating that way like "ok, now I've got THIS to deal with too." Instead it's understanding an overall process and whatever hurts next is just next in line in the disease process.
All that having been said, My U.C. had a very large autoimmune part to it. Didn't respond to anything but extremely high doses of imuran and prednisone.. so once the colon was removed, what were all those overzealous antibodies to do? Well, attack other parts of my "healthy" body. In this case its my joints, resulting in arthritis.
That's not to say that some people have a true dual problem... I.B.D., U C, arthritis, or some other malady entirely separate. I just think it's too related to be distinct and separate things going on.
I think different people's exact experience and pains may be different, and SOME people may have just had an autoimmune response to their colon, but what ever the case, for me it wasn't just a disease of my colon, and now a disease of my joints, it's an overall disorder which doesn't have my good ole colon to attack anymore, rather it's moved on to another body system.
Does all that make sense?
