Im ok now that I took some good pain killer. It happened when I was drilling out a rivet on a 90 degree steel bracket. I didnt have enough room for pliers so I used my hand . I didnt have my hand over the rivet, just next to it but, the drill poped through the hole because I was using to much pressure and I hit My hand at full speed. Thats an 18 volt Dewalt as fast as it will spin. So I hit my middle finger and I started oozing blood. Dumb me, I wiped it off on my pants and wrapped it in masking tape so i could keep working. After about an hour the tape was soaked a dripping and I had blood everywhere. So I got some peroxide and cleaned it out. Thats when i noticed I went to the bone, I could see my insides, and I think I cut the tendon because I cant bend it well. Oh well, just anther story.
