Hi Philip, thanks for writing to us. I am sure after a long course of heel problem, you have already known the diagnosis of your problem is plantar fasciitis. You have gone through nearly all possible treatment of the problem, except for deep massage and steroid injection. I understand your frustration because I am also a patient with plantar fasciitis. I was lucky enough to have gotten well by just using silicon heel pads, which you may have already tried. My wife also had this problem and she was less lucky and she eventually have to be injected by me with steroid. She was able to go back to her duty the next day. Local steroid injection is safe over the heel pad. I have done many times for patients and most of them have been gratifying.
