I had an abscessing signoid colon and had surgery
and, well, it wasn't gas.
But over the years I keep getting, well, weaker, more off balance, double (and triple!) vision, horrible dizziness, etc., and the one that is in some ways most difficult for me is occasional incontinence. It started with having to get up every fifteen minutes during the night to go pee. Not always, but there would be periods of this. Well, I didn't want to tell anyone about it.
I have epilepsy.
