Plantar fasciitis is a common foot condition that causes pain in the heel and the bottom of the foot, particularly noticeable when taking the first steps in the morning or after periods of inactivity. The pain is due to inflammation of the plantar fascia, a thick band of tissue that connects the heel bone to the toes, and supports the arch of the foot. Overuse, inadequate footwear, and excessive weight can all contribute to the development of plantar fasciitis. Treatment typically involves rest, stretching exercises, proper footwear, and sometimes orthotics to alleviate pressure. More severe cases may require physical therapy or other medical interventions to reduce inflammation and promote healing.
