Ditto what quincy and princesa said. You might need to try a different ASA as different ones work better for different people, but I also think you should be on a rectal med. I had a really bad first flare (15-20 BMs/day at my worst) and almost got into remission using Asacol and Rowasa (mesalamine enema). Then I got a tummy bug, which threw me back into the flare. As I had a big interview coming up and HAD to be well, my doc prescribed a pretty quick course of pred, which luckly, worked. I stayed on Asacol and Rowasa the whole time.
