wow 2003, ummm, well if your uncle is still kiking he probably knows by now.The doc's really didn't want to give me much answers either, all I know is I take the medication they gave me for crohn's and I'm mostly fine now after two years. In fact it's "cleared up" and I may even be able "to stop the medication soon". I take a drug called Pentasa and it has worked great for me. I noticed that others take some different drugs and have some complaints? not that your likely to read this now anyway
