There's probably no worse non-serious injury that jamming your finger in door, drawer, or something similar. And it's not just about the excruciating pain that occurs the moment it happens (which is the actual worst), but about the months it takes for the injury to heal.
Provided that your nail doesn't actually fall off (which is super gross), you'll likely get a large black spot (under-the-nail bruising) that looks super creepy and simply isn't something you want to see when you look down at your hand. This person decided to get a little creative with this obnoxious injury, and put together a series of photos: One for every day it took for his thumb to grow out. The craziest part? It took over five months.
