inflated malleolus area

[soniczip]

since a not properly secured door bar hit the lower part of my right shin on the 26th of july, the area around my right malleolus is a bit inflated. it doesn't hurt and that's probably why i realized only a week after the injury. i can run, cycle, jump, whatever ... it doesn't hurt, but the inflation is still there. maybe i should rest or take something? has anything similar ever happened to you?
