A heel spur is an extension of the heel bone that extends into the tissue directly in front of the heel. It is most often a result of chronic plantar fasciitis.
A heel spur can be seen on an X-ray as an extension of bone in front of the heel.
Treatment of a heel spur involves treatment of plantar fasciitis. It includes stretching exercises, possibly the use of a splint, or anti-inflammatory medications. In some cases a steroid injection is given directly in front of the heel.
The pain due to the plantar fasciitis that causes the heel spur can become progressively more severe, in some cases damaging the tissue.
