I'm not a student at Gordon anymore. I graduated a long time ago....I just kept my e-mail. My heel feels fine in the morning. It only hurts after running and lingers for the day. My foot feels better when I walk around barefoot.
Then it is unlikely you have PF. Morning pain and stiffness after a few hours of inactivity is a hallmark of the injury. This is because your plantar aponeurosis begins repairing after inactivity, and resumption of activity reinjures the aponeurosis. This is why PF is a stubborn injury which is difficult to treat, and explains why the Strassburg sock works (it pulls your foot into dorsiflexion and extends the digits, so any repair to the aponeurosis occurs in the extended position). PF sufferers typically do not experience pain after running except in severe cases.
To be honest it could be many things, As I mention above, quite a few muscles originate from the tuberosity of the calcaneum - you may have injured one or more of them. The foot is wrapped more or lss top to toe in various tendons and ligaments, any one of which could be causing the problem. A podiatrist should be your next port of call.
