I'm no expert (there are lots better on here) but I'll give you my two cents.  Is the pain actually at the very back of the heel, where it turns to go up to the ankle?  The bone spur could be causing most of the pain.  Heel pads may help.  Are you a heel-striker?  I had pain at the back of my heel (not plantar fasciitis, though my podiatrist was convinced it was).  I "fixed" the problem by changing, over many months, from heel-striking to a midfoot plant.

If you've posted this question/situation on runnersworld.com then you've already seen my answer.     The description here is remarkably simialar to a posting there.  But on the chance you haven't posted on runnersworld.com - you might check out ASTYM.  ASTYM is administered by certified PTs.  The technique involves scraping the skin with plastic instruments.  The scraping causes micro trauma to the tissue underneath - causing the body to go into healing mode so the tissue can be remodeled and rebuilt.  From what I understand the technique works very well on tendons.  I had it done for Plantar Fasciitis and it worked very well.

Good luck.

I have something similar in my left foot which my Dr insists is PF but is not at all similar to the PF I've had in the past.  I have pain/ache around the outside and inside of my heel.  Right under my heel, something pops while walking (you can actually hear it popping) and my ankle cracks nonstop.  Any ideas?  Haven't run since July 2010.  Doing P90X now which only stresses my foot on yoga days.  Thanks for any input
