I slammed a door on my big toe while wearing flip flops about a week and a half ago. Under my nail is a little sliver of blue - I think that's blood because I poked it thinking it was dirt and it bled. Anyway, I'm worried because it's still very tender to the touch. Although I've been walking on it since I hurt it and it's not crazy painful. Should I go to the doctor or just let it heal? I know YANMD but just curious. I can afford to go to the doctor but I just don't want to take an extra trip.
