i went running on sunday, and about 4miles into it, my arch started hurting, i have high arches, and then the next day i had a bruise, its still sore, no heel or ball of foot pain, ice has helped, im concerned that its plantar fascitis, but no other clinical symtoms. no pain at rest, i have pain walking, and i haven't run since. I don't recall landing on anything while running, i run on the balls of my feet.
