i wish you all the luck in the world, you can do it!
i'm dealing with somewhat the same issue except it's my knees. i'm not a runner but ADORE very brisk walking on my long dead end road at night with my music blaring in my ears and stars above. All that changed when my knees flared with what i think is a fibromyalgia/RA and who knows what else flare! it's DEVASTATING.
All i can say is pay attention to your ankle and take it slow and when it STARTS to hurt then back off, you don't want to go all the way into immobility.
