What would cause sharp jabbing pains and burning pain in the heel area of the foot. I have had 2 plantar fascia release surgeries in 8 months same foot. The pain is somewhat different, Now it is more when weight bearing and in the ankle as well. Before it was worse in the morning on first walking. Now it is constant. My nerve conduction test did not show much and regular xrays show nothing as well. I also had a fibrous tissuse mass removed from my cuboid area. Please let me know what you think.
