Nicole, it is possible you have a good old fashion case of tendonitis? I've had two cases of in my left ankle the past two riding seasons. It appears, after my recent bike fitting, that each case was due to three things, incorrect cleat placement, incorrect seat placement and the simple fact that my left leg is shorter than my right leg causing me to hyperextend my left leg/ankle.

To treat both cases my chiropractor had me ice the area 5 -6 times a day, use some gentle stretches. Also, this year my foot doctor added some arch supports to my inserts along with a low dose of an oral antiinflammatory. I was told it was okay to keep riding as long as it did not hurt while on the bike.

Hope this helps and your heal quickly.
