How soon to start running on mildly sprained ankle?

[cindyluwho]

Hi,

Oops, I hit the wrong button...I just sprained my ankle very mildly the other day, and am wondering when I can safely start running on it again? This is my 6th sprain on this ankle, and with the exception of the last time I sprained it (it was quite severe so the orthopedist plastered a cast on it, rendering it completely immobilized for 4 weeks), I think I usually have started doing stuff too soon after my injury because it never seemed to heal properly. I'd like to know how soon I can start running without hindering the healing process. Right now, I can walk with almost no pain with the air cast on. It's a bit weak without the air cast, but I can walk on it if I'm very careful. Any recommendations?
