Accidentally had a door slam on my hand at work a couple months ago. The bad nail is growing out and a new one is trying to come it. It's all just very gross. So I have a wiggly damaged nail waiting to grow out and fall off. Until that moment comes, I can't really do much with it but put a band-aid over it to hide the ugly.
I guess I can try to use my left hand to paint on my right... I'm just not very ambidextrous.
