I can sympathize with you, as I am currently going through similar symptoms, and have been flaring since August, ugh! Hang in there, and be open to new medications, as this can be necessary. My flares were once controlled by Asacol alone, and now you can see how much crap I'm on now!! I think it's best to try new meds right away, before the flare is too out of control, and prednisone no longer works.
25, Diagnosed with ulcerative proctitis 7/2006

Current Treatment: Asacol (3pills 2X/day), Rowasa, Prednisone (currently on 35mg, tried tapering multiple times since September 2008 to no avail), Imuran 50mg, Ultimate Flora probiotics, digestive enzymes, beginning Remicade once I clear my testing
Status: Worst flare so far, since August
