I have pain on the back of my left hand, about a half inch diameter spot just before the knuckle of my index finger. It feels like a broken blood vessel or a bruise when it first happens.

It happened for the first time about a week ago, painful to the touch, and figured I'd whopped my hand against something. I expected a bruise to appear, but none did. And it went away.

It started again yesterday and is worse this morning. Nothing visible, little or no swelling, but if I press lightly on it or twist my hand a certain way, the pain curls my stomach.

Anybody have anything like this? I tried to google stuff, but my brain is still fried from Christmas. Hurts like sin.
