I have had on and off rectal bleeding for the past 9 months with mucus and a lot of urgency. I went from having one bowel movment a day to 3-4 and it is almost always diarhea like. Blood tends to be scant and bright red and but lots of slime and stuff. I had sigmoidscope done awhile back which didn't find UC but it seems like I have all the symptoms. maybe they missed it?
