Hi CDM
Reading your post reminds me of myself in a way. I think I had UC for many years, but went undiagnosed because by the time I had a scope done I was already in remission or the doc didn't know what he was seeing (lived in small town with small town docs). It really flared 2 1/2 years ago (shortly after I quit smoking and lost lots of weight).
I am on my third doc now since being diagnosed and will probably be looking for a new one soon, as this one just does not communicate with me. I have learned so much more from these forums, than I ever did from two of the three docs. (The one I liked moved).
The doc I liked said there are two approaches - start at the bottom with the rectal meds and stuff or start at the top and hit it hard.
Each of the three doctors saw something somewhat different when they did the scope, and I really do not have a good answer for that either - # 1 said left sided uc. #2 (the one I liked) said pancolitis. #3 says left sided uc.
Doc #1 said take Apriso and see me in 4 months. He didn't respond appropriately when Apriso caused me unstoppable urgent watery d. (Which I didn't have before his colonoscopy). Doc # 2 did all kinds of blood tests which showed all kinds of vitamin deficiencies and blood abnormalities as well as CT scans and MRIs which also disclosed a kidney cancer. She had me try canasa, rowena or something, 6mp, but only prednisone helped. Doc # 3 has me on 6 mp and remicade.
I have gone through all the meds and am ready for the surgery, as I am in such misery all the time.
Read everything you can from these and other forums, so you know what you are dealing with and be sure to have a doctor you can talk to. If you have to go to a bigger city, it is worth it.
