About a month ago, I tripped on a the side of a door and fell. My ankle hurt only when it hurt and only on the side part of my ankle where the bump is (sorry I do not know correct terms!). Well two weeks later I hit it against something and it hurt and I realized that there was an actual bump on it and when I touched it, it hurt. I didnt pay much attention to it because it didnt hurt when I walked at all. Well last night, I was laying in bed and it just started to throb and the pain wouldnt go away. Then I could feel that the area where the bump is, started to fall asleep and then the rest of my foot fell asleep. I do not know what is wrong and would hate to go to the doctor if nothing is really serious. The bump is noticeable when you look at it. Any clues on what this could be?
