Four days ago I slammed my right thumb in a car door, and there's been blood under the nail ever since. It doesn't really hurt if I don't touch it or anything, but the backside of my thumb is very swollen and tender. Because of this I can't really use my finger, and I've kept it in a splint. However, school starts in a week and I want to be able to write (legibly), which I can't really do right now. So my question is this: should I go to the ER and have the blood drained or is it too late because the injury happened on Sunday? Also, is the process painful and would I be able to play soccer in the days following? Thanks!
