I've been tapering down from 40mg of prednisone, and when I made it down to 10mg I started feeling sick again. I went back up to 12.5mg and when that didn't work I went up to 15mg. I've been on that almost a week, and I've noticed small amounts of blood in my stool a few times. I've only ever had blood in the stool when I have been having a bad flare. Is it possible that I am flaring up again even on the prednisone? Should a person have blood in the stool when they're on pred?
