Foot Pain

thisisjl

Ok so I've been trying to just work through and stretch it out but I've got this incredible burning/stretching/pain in my left foot where the arch combines with the heal. Not the center part of the arch but just before it joins the heal. It hurts to walk on it and REALLY hurts if I press on it. I thought originally it was from wearing wedge sandals two days in a row but that was a week ago and I've worn good tennis shoes all week and it is getting worse. Any ideas what this might be it's causing me to not work out nearly as much as I'd like. I will have it checked out by a doctor if it doesn't get better soon but I'll be out of town the next 3 days.
