Good news/bad news:
Good news - MRI went OK. I won't know results until this week. But it may be a moot point...
Bad news - There's something very wrong with my pouch. I don't know if it's another abcess, a badly behaving adhesion, or what, but there's very local pain and swelling around the stoma. I'm calling the surgeon who fixed me up last year to see if he can get me in to see what's wrong.
So right now I'm playing a lot of Diablo II, killing demons and crap. Helps the mood.
