I sprained my ankle last Sunday, 7/9. Right off the bat I could tell it was pretty severe. After icing it on the sidewalk for 20 min, I could not even touch the pavement w/ my foot. That night I went to the emergency room and the doc took some xrays and told me it was not broken. he gave me a cast (air-cast?) and a pair of crutches, told me to ice it regularly, and keep it elevated and that the swelling show go down in a week. all pretty standard stuff. its been about 5 days now and the swelling that was concentrated around my ankle has disappeared, but appears to have spread all over my foot. put simply, my foot is fat. when i try to move my toes, they get caught up on one another. also, dis-coloration in random patches are appearing on my foot. the dis-coloration looks like bruises although they do not hurt. i read about ankle sprains on the web and one website broke it down into categories where a category 3 ankle sprain would be characterized by torn ligaments. i'm pretty sure ligaments do not appear on x-rays and the doctor did not mention anything about this. my foot looks awful although the pain has subsided considerably and i can put more pressure on it now. should i be worried about torn ligaments? anyway i can tell if my ligaments are torn or not? should i be worried about my the mammoth size of my foot? i don't have insurance and the emergency room is already going to cost me a fortune. any advice or diagnosis would be appreciated. i can post or email pictures if desired. thanks in advance.
