About 2 months ago I burnt my finger tip right where the nail and fingertip meet, it started to heal like normal and then one day I hit it on a table and it started bleeding pretty heavily. Since then, a large red bubble filled with blood and tissue has been forming and coming out of the skin. I've tried popping it and only blood comes out. I've tried compressing it and within 10 minutes of taking a bandage off it pops out of the healing skin. Is this at all normal? Any suggestions on what I should do?
