Heel spurs are bony outgrowths positioned where the plantar fascia tissue attaches to the heel bone (the calcaneus). Heel spurs seldom cause pain. It is the inflamed tissue surrounding the spur that causes the pain. The Latin meaning of Plantar Fasciitis is, “Inflammation of Plantar Fascia.” The plantar fascia is a long, thick and very tough band of tissue beneath your foot that provides arch support. It also connects your toes to your heel bone. Each time you take a step, the arch slightly flattens to absorb impact. This band of tissue is normally quite strong and flexible but unfortunately, circumstances such as undue stress, being overweight, getting older or having irregularities in your foot dynamics can lead to unnatural stretching and micro-tearing of the plantar fascia. This causes pain and swelling at the location where the plantar fascia attaches to the heel bone. As the fascia continually pulls at the heel bone, the constant irritation eventually creates a bony growth on the heel. This is called a heel spur.
When the Plantar Fascia is allowed to rest during sleep or long periods of inactivity, the fascia tightens and shortens. When you first stand up after resting, the fascia is forced to stretch very quickly causing micro-tears in the tissue. This is why the first steps in the morning are so exquisitely painful.
Heel spurs are more likely to happen if:
- you suffer from over-pronation (walking with a rolling gait)
- you stand or walk on rigid surfaces for long periods
- you are above ideal weight or during pregnancy
- you have stiff muscles in your calves
