Hi Happy. My advice is if you found the Canasa helpful, stick with them. I personally did not like Canasa because it seemed to make me have more diarrhea than before, but the enemas take some getting used to and I wouldn't quit something that seemed to be helping. I don't think 20mgs of Pred is that much, from what I understand, the very highest doseage is 60mgs. I was steroid dependent for about
a year, the only way I got off the steroids was by myself and my UC got worse. At the time, I could not stand the side effects of the drug and didn't care (as much) about
my UC. I do not reccommend you changing any doses of meds without your doctor's approval.
Ok about the scalp; it may be Psoriasis, I have sores on my scalp when I am flaring, to me it means that my inflammation level is high. I saw a dermatologist and she gave me a medicated foam which worked for a short while. Have you shown them to your GI? I used to only talk about my butt to my GI, but now I know it's useful to tell them everything else going on as well, some things are UC related and I would have never guessed. If you have any other questions, just ask.
