(((((TriGirl))))) sending good thoughts for healing and pain-free running!
....just curious though and it really isn't something I know much about. But I dealt with Achilles issues for years (still do to some extent), which seems to be closely related to plantar fasciitis. I tried all kinds of treatments too, but it's only form work, plus changing the type of shoes I wear for aerobics, (re-injury prevention) that's finally got me on the road to recovery. Have you had a PT really look at your form (not just running but in your other sports)?
