hi when i got kicked in thigh by horse the pain had subsided by two weeks i would go back cos it could of damaged nerves tendons etc and you shouldnt have swellling round ankle if been hit in thigh
You should go back to the Drs. I was in a car crash a year ago, they xray-ed my wrist and said that it was fine. After two months of pain I went back and they did another, and they said that it had been broken the whole time. Sometimes the fractures do not show right away do to inflammation from the accident.
You need to go back to the doctor. It doesn't take much of an injury to possibly cause a blood clot. Since you have a swollen ankle, it makes sense to go back to the doctor and rule this out. Blood clots can be dangerous and need to be tended to immediately. I'm not saying this is what you have but it is worth getting it checked out.
