I've had the IBS since I was a kid as well. I had some embarrasing issues when I was a kid. It wasn't until my knee sweeled up to the size of a canteloupe that I was diagnosed with Crohns. I was 20 at the time. I'm 41 now. It definitely explained why I had such bowel issues, but noone knew about
these things 30 years ago.
I was on prednisone for the better part of 5 years. For the first few years it ws on an as needed basis, I wsa allowed 15 mg a day. I probably averaged taking about 15 a week for the first year or two. At that point I hit a wall and I seemd to have nothing but bad days. My rheumy put me on 15 mg a day every day. I stayed on that for 3+ years until this past May. I had just the opposite reaction to the steroids, I was hungry all the time. No matter what I ate, I was hungry a few hours later. I've got a much more normal appetite now.
I'm a big guy and have been for a while, can't blame it all on the prednisone or the arthritis but they sure didn't help. I was a hyper active kid and now I'm more of a couch potato. Hard to be super active when every step you take hurts. I'm 6'2 and 250 now, I got up to 280lbs when I told my Rheumy I had to get off it. He said OK if I could take the pain.. The pain has gotten worse, but at least I'm heading in the right direction.
