A heel spur is a bony growth which is found either at the back of the heel or underneath the heel bone. It is built up from a calcium deposit that will protrude out from the foot, up to half an inch towards the arch. The primary cause of heel spurs is a common foot complaint called Plantar Fasciitis. The Plantar Fascia is the tendon that runs along the underside of the foot and connects the heel to the toe bones.
Heel Spurs can become inflamed or aggravated, which can cause pain when walking or putting any weight at all on the area. Alternatively, a heel spur can develop from inflammation of the Achilles Tendon.
The pain associated from heel spurs is usually experienced as a sharp pain on the underside of the heel. This is most notable on the first steps after getting out of bed. Often a little walking helps reduce the pain, but prolonged or intense movement will make it worse. This can make heel spur treatment difficult.
