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. However most often insole therapy can help with eleviating the pain and reducing the pressure through the foot by support in the area in hand.
The pain due to the plantar fasciitis that causes the heel spur can become progressively more severe, in some cases damaging the tissue.
