I have really banjaxed my foot. For some reason, i still can't quite figure out how the hell it happened, i sat down on a whirly computer chair with wheels and as i sat down on it one of the wheel ran over my foot. it really hurt and did for the rest of the day i could barely walk on it. i now have a big bruise approx 10cm x 3cm just below my toes on the top of the foot and it stings so much. Could i have broken it? I have never broken a bone before and im quite a big girl and my whole weight went down on the chair before i realised wtf had happened. do you think i should just leave it or go to a&e. its also quite swollen.
