The plantar fascia is the part of the foot that acts like a shock absorbing bowstring, supporting the arch in your foot. Plantar meaning the bottom side, and fascia is the name of the tissue in this area. Fascia is not muscle, not bone, not cartilage, not ligament, not tendon, it is a tissue all it’s own. This fascia tissue is made up of billions of tiny fibers similar to the fibers in a piece of elastic or Lycra. If the tension on that bowstring (fascia tissue) becomes too great, minute tears can occur creating pain and inflammation. The result is foot pain. Foot pain is no fun.
The average person walks the equivalent of three times around the earth in a lifetime. That is an enormous amount of wear and tear on the 26 bones, 33 joints and more than 100 tendons, ligaments and muscles that make up the foot.
