Running on Empty.: It sounds like you are having some trouble with the medial band of the plantar fascia. The symptoms are consistent with plantar fasciitis, a type of overuse syndrome. Until you get control of the symptoms and change your workout regimen, the symptoms will undoubtedly continue or increase. Best to consult with a foot specialist.
