a midway bikelog

Seeking some lazyweb medical advice, if anyone has had experience with injured hands. During the 12-hour race early this month, i had a near-crash during which the handlebars bashed my right hand pretty good from the outside of the knuckles (as if i were punching the bar, my hand came off momentarily). My whole hand was normally sore for a day or two, but the middle finger knuckle at the base of my finger still hurts, and it’s been almost a month. I have full range of motion and grip, but it sometimes still hurts to touch my palm with that finger. It doesn’t seem like there’s anything to do other than splint it, but i don’t think normal activity is hurting it. Time for an x-ray? Or just a slow-healing thing? I hate having a middle finger out of commission so long…
