I guess having four polyps cut out of your colon isn't a totally trivial matter.
I've had a lot of abdominal pain ever since, and have just had general fatigue. Also, I've had a headache I can't get rid of, and I'm not allowed to take aspirin or Advil until Friday.
I did say over the past month or so that radio might not happen this week, and indeed that's the situation. Tentatively, the next radio will be on Friday, January 29.
I am eating normally and don't have a fever, so I'm not all that worried. I have a feeling that cutting the big polyp at the farthest inside point of my colon probably is causing my body to react to the irritation.
