Plantar fasciitis is a common foot condition that results from inflammation of the plantar fascia, a thick band of tissue that runs along the bottom of the foot and connects the heel bone to the toes. This condition is often caused by repetitive strain or overuse of the plantar fascia, particularly in people who engage in activities that involve a lot of walking, running, or jumping. Other risk factors include obesity, high arches or flat feet, and tight calf muscles. Symptoms of plantar fasciitis include a stabbing pain in the bottom of the foot near the heel, particularly when first getting out of bed in the morning or after sitting for a prolonged period of time. Treatment options for plantar fasciitis include rest, ice, stretching exercises, and over-the-counter pain relievers. Custom-made orthotics may be necessary, and in rare cases, surgery may be recommended.
