Sick day

Inexplicably I developed gut pain last night around 7:30 p.m. which kept me doubled over in pain. I don't know what caused it. I wasn't feverish or nauseated. It just hurt if I turned over in bed or tried to straighten up.

Spent the day curled up in bed reading. It's easing now, and I expect I'll be able to go back to work tomorrow.
