A few years ago I stepped off a step wrong and hurt my ankle. I iced it, and everything, but when it was still swollen and sore a few days later I went and had it x-rayed. I was told it was not broken. While in the exam room I noticed a bump directly under my ankle bone. I pointed it out to the doctor and she told me that I probably always had that and just did not notice it. I was 25 at the time, I think I would have noticed a bump that sticks out almost as far as my ankle (especially since I have bony ankles). I was give an air cast and sent on my way.
Now whenever I am on my feet for too long, or like the other day I ran 5.25 miles on an eliptical machine, my ankle will swell and this bump will stick out more. It usually goes down in 12-24 hours with or without ice. This time is not going down even though I have been icing it for two days as much as I can. The pain is a pretty intense burning pain that is not starting up the outside of my calf muscle. I do not want to go to the ER to get it checked out if there is going to be nothing they can do about it. I have insurance, but it is not all that great.
