my wife started running about and has developed a pain in her right foot, to be more precise its starts in the heal and seems to radiate to the arch. when the pad of the heal is squeezed at the sides with thumb and forefinger it is tender , the pain doesnt radiate round the heal to achilles. she also says in the morning when she gets up or if shes been off her feet it feels very stiff until shes moved about on it then it eases for a while but during the day turns into an ache and then gets more painfull as the day goes on. she runs 4 or 5 miles 3 times a week on flat grass or paths and the occasional trail. ive never suffered with pf or any other foot injury so dont really know what this is got the odd theory but was hoping the combined knowlege of the forum could help and id it
