Ouch

Ran 10 miles today and my left ankle was hurting the entire run, more when road was pitched.  Tuesday I did a track workout, and usually after a track workout my left ankle hurts from running all the turns, but this was different. I just hope it isn't something more then just normal pain.  Some background info on my left ankle, in HS I sprained my left ankle while playing basketball.  I was going up for a layup and came down on someone's foot and turned my ankle.  The Dr told me that it would have been better to have broken it then the sprain.  I was on crutches for weeks and went to physical therapy daily for at least 2 months.  Ever since then, I sprain my left ankle at the drop of a hat and it gets sore very easily.
