Two days ago I was putting on a Christmas pin when I accidentally pushed the pin into my finger, right by my nail. It did not bleed, but did hurt a lot. I didn't think much about it, but last night (24 hours later) my finger started to really ache at the second joint. It hurt to bend it, felt a bit warm, so I thought I must have hit it. The next morning it was swollen through the middle of the finger. Still hurts to bend, and is a bit warm to the touch. Is it an infection? There is no discharge from the puncture site, in fact, all looks well by the puncture site, and I have no red streaks. Any ideas?
