Hi Lucy,
I can relate to some of your medical issues. I have crohns and have had one resection, then in June of 05 I was dx'd with UC. Fun, huh. Last year a rheumy dx'd Lupus. I told my gi I just didn't think my body likes itself, it stays in a constant battle.
Are you on any medication for your UC? My gi immediately put me on Lialda and I have been on it ever since I got dx'd. For the cD I am on 100mg of Imuran, Entocort. I just recently went back on Remicade for an abdominal fistula.
Are you not being followed up by a gi dr? I am sure you know your UC can cause joint pain, fatigue and many other problems, just like the crohns can. I know you don't want to see another dr, but Shannon is right, you really need to consult with a rheumy/ just do it and get it over with,lol. Lots of hugs coming your way. Susie
