Hello, so im not sure if I broke my foot or not.. 6 days ago..a big rock fell on top of my foot..and instantly swelled up to a golf ball...maybe a little bit bigger..now the swelling has went down...and it is in the bruising process.....it hurts a lil to walk on..but not very much..I know I didn't break my toes..or sprain it..but I was wondering If maybe I broke one of the tiny bones on top of the foot? And how long will it heal?
