Please state the nature of the medical emergency

Friday morning’s “gas pain” turned out to be diverticulitis (does involve the lower G.I., so the Wikipedia link may squick some folks). After a day of agony, I ended up in the ER until 4 a.m. where the doctor was thankfully able to diagnose me immediately. I’m on antibiotics for the next few weeks, and I have to give up peanuts only months after finally learning to like them.

My system’s still a bit rattled from the fever and pain. I’d rather stay home another day or seven, but duty calls.
