HI! I just want to welcome you to the forum!
I would love to advise you on your concerns, but everyone else gave GREAT info before me.
Ill tell ya a bit about me, I thought I had the stomach flu when I was first diagnosed. The thing that finally got me to the doctor was the unrelenting severe stomach cramps I was getting. I thought the blood I was getting was due to hemorrhoids or the IBS that I had in the past. But when I came to work, and couldnt' do a thing without the WORST stomach cramps ever, my team leader sent me to urgent care, and so my journey of blood tests, flex sigs/colonoscopys/biopsys, and meds began. I had to try several meds to get me in control (still trying to be sure I"m on the right maintenance meds). But until recently, for the acute flare ups, prednisone always did the trick of getting me feeling better. Then for maintenance had to find the right combo. Hang in there, hopefully you will feel better soon.
This forum is a Godsend!! It is so reassuring and comforting to talk with people that truly understand exactly what your going through. (I could most honestly feel your pain as I read your message). Also great resource to find out info....again, hang in there!! We're here for ya!
