My foot was ran over by a 4 ton fork truck and I went to hospital and got it x rayed there were no broken bones. however my foot is swollen like a balloon and the pain is incredible, I've had pain killers and it's done nothing and I can't sleep due to the extreme pain. My main problem is that I cannot walk or put any weight on it at all and I was wondering what I should do as I need to be able to move around my house, please help.
