hi, just got out of the shower. 15y/o male here. it was a few minutes before I noticed it, but there was a weird oddly colored bruise like pimple/bump on my finger about the size of a sesame seed. If that. At first glance it looked like a splinter, but the more I picked at it (the wrong thing to do, I know now) it opened up and started bleeding. Not too much, but it alarmed me at first. It definitely wasn't a splinter, haven't had anything like that before. I immediately went to wash it off and everything, and now I'm here typing this with a very tiny hole in my finger. It stopped bleeding, though. I'm still concerned. Anyone know what it was? Thanks!
