I completely disagree that you need IV steroids. You are having very minimal symptoms right now and IV steroids are pure hell side effect-wise, for me at least (they make my emotions go absolutely insane...bawling in the hospital, etc.). I also don't know any doctors here that would appreciate you marching in and telling them you want IV steroids (you can know what you want, but you still have to play the game and be tactful with most doctors because most don't really like being told what to prescribe to a patient). I can't imagine that ever happening with IV steroids in the U.S. unless a hospital decides to admit you. Most ER docs know nothing about
UC. Last time I went to the ER, thinking I'd be admitted, they gave me one dose of fentanyl (which barely touched my pain and only lasted maybe 2 hours) and 5 (yes, 5) days of prednisone and sent me on my way!
Ruling out Celiac Disease is a good idea, but I doubt you have that because you would be extremely sick after eating any gluten from what I've read. I did have it ruled out when I was first diagnosed though.
You could up your pred back up to 10 mg and see if that helps. What other meds are you on again? I forget if you are on rectal meds? You can ask your doctor for Zofran for nausea. It helps sometimes.
P.S. Love the post name typo.
