Have noticed a little sore spot on my right hand the last couple of days, but thought little of it. Late last night (after my gig) felt some increasing soreness. This morning, began noticeably swelling. Seems things like this happen on a Saturday, which allows us to keep in touch with our friends in the ER. Upon leaving the house, I was aware the two possibilities were stress fracture, and some kind of infection. The latter was the definite best option, for obvious reasons, which turned out to be the diagnosis, thankfully. Yes, kind of sore, but not enough to keep me from practicing after visiting the pharmacy :)
