Plantar Fasciitis (pronounced PLAN-tar fashee-EYE-tiss) in its simplest definition is an inflammation of the plantar fascia – the connective tissue on the bottom of the foot. The inflammation occurs in the connective tissue at the heel pf the foot. As a result of this inflammation, heel spurs develop in the area. Heel spurs are malleable calcium deposits that can be easily seen and identified on an x-ray. Heel spurs are NOT the cause of pain for patients (the inflammation is), but because the spurs are readily identified, the terms plantar fasciitis and “heel spurs” are used interchangeably for convenience.
