What am I supposed to do about this injury?

When I injured my fingernail, the pain hurt for about two weeks. My nail ended up growing back six months later, so it does take time for a new nail to appear. If you are going to end up working, I would suggest getting some finger splints and putting those on the injured fingers and then wrapping adhesive medical tape around the splints to keep them in place. This should protect the fingers when you are moving heavy items. There are some splints that cover the nail, so you may want to invest in that kind of splint.
