There is a way to tape your heel, which will instantly reduce or remove the pain.  I can do it, but it is difficult to describe.  Basically you support the heel pad so it does not "spread" as much.  Like I said, hard to describe.  See a doc. or physical therapist.  I had it so bad I could not walk.  The taping removed the pain and repaired the damage done.  Now I am entirely free of symptoms.
