The plantar fascia is a piece of strong and thick tissue that runs along the bottom of the foot. It connects the heel bone to the toes, creating the foot's arch. Plantar fasciitis is inflammation of the plantar fascia, either through overstretching, overuse or a medical condition.
What Causes Plantar Fasciitis?
Plantar fasciitis is most commonly caused by repetitive strain injury to the ligament of the sole of the foot. Such strain injury can be from excessive running or walking, inadequate foot gear, and jumping injury from landing. Plantar fasciitis can also be caused by certain diseases, including reactive arthritis.
