Well look at it as a learning situation...if/when it happens in a SHTF scenario, you will be able to deal with it....I've done it too...the one next to the big toe! tripped on the dog in the dark! Silly I know!
If the bruising is in a ring all the way around the toe, it's broken. If it's just on one side, it could be a bone bruise - which can be even more painful. Either way, elevate it and put an ice pack on it and take advil.....hope you feel better!
