Running Injury (?)

Well. That didn't end well. Finally my ankle and knee issues have sidelined me. I'm pretty sure I've done something to my MCL, probably when my ankles were bothering me. The MCL seems to be getting worse, but the ankles aren't. I did the 3 minute run today, but after my knee felt completely WRONG at the *walk* after that, I probably have to get it checked STAT. So frustrated.
