What a sweet response. Thank you.
I heard from the doctor and the diagnosis is "only" proctitis. Guess I was reading the internet too much and was worried about the cells being pre-cancerous. Need to stay on canasa for a couple of weeks and then use it as maintenance every other day.
I asked him about probiotics - he said they can't hurt, but he believes that if they help at all, it's only a tiny bit (of course, he didn't say tiny bit!) Have used culturelle in the past and wondered if you think it's doing anything for you. I'm a big believer in "complementary" medicine so am open to trying again, but can't imagine how I would know if it helps. Kind of costly too!
Thanks again for the lovely welcome!
