I twisted my ankle while jogging a few years back and it was 2 hours before I had to pick up my son and my hubby was out of town. Of course, I didn't go to the doc and my ankle was so swollen/black and blue. By the time I could call the doc, there was nothing he could do (I had already wrapped it). I also found out there is more of a chance you could do more damage to the ankle, but knock on wood, that hasn't happened yet.
