UC is usually diagnosed by a colonoscopy with tissue samples taken. If tissue samples were taken during flex-sig, your pathology report will tell you what type of colitis you have (sometimes "indeterminate").
Did you have stool samples examined?
Your treatment, in part, depends on the type of colitis you have. How did your M.D. determine your condition was/is UC? And yes, upper GI symptoms such as gas, bloating, cramping can be a side effect of Mesalamine especially if you were asymptomatic prior to taking them. It does take time for them to work though, so often you may be prescribed steroids to help quiet the inflammation until the Lialda and/or Canasa kick in.
Regardless, you came to a great forum with lots of valuable advice. Be sure to take advantage of the search box on the upper right of your screen--it will search within the forums.
In my experience, during a flare, the discomfort is daily and progressively worse. But if you're "simmering"--heading for a flare, or just coming down from a flare, it is common to have a few good days followed by worsening symptoms. It all depends on the degree, extent and location of your inflammation. Try to get a copy of the pathology report when it comes.
It's not bad if you skip a bm occasionally (wish I could). Ask your PCP about the imodium.
