I have had a dull aching pain on the top middle of the foot. The pain starts about a half inch from the base of my toes and is very centralized. I just went for a 4 mile run and now it is throbbing and a more intense pain. I do not lace my shoes very tightly because I lose circulation when I do. I do wear Innov8 shoes, which are minimalist shoes, and I have been running on a treadmill with an emphasis of trying to run on the balls of my feet rather than pounding down through the heel.
There aren't any physical signs of bruising, but it does hurt if i press down on the area of the foot that is affected.
