I received a cortisone injection in my heel area 3 months ago near a bone spur. This helped my heel pain but now my arch feels as if there is a gel in the area - when there is pressure on the spot it becomes very sore. This pain moves around the arch of my foot and the more pressure I put on it the more it hurts. I have tried taping as well as a lace up brace to stabilize the foot but the sore area just moves to just on the outside of the taped or braced area. I feel this may be an edema in the foot and it was triggered after the cortisone shot. Is it possible to have swelling this long after the shot? I do stretches every other day for the feet and do not have a problem with tight tendons. The bone spur was caused do to an injury.
