Plantar fasciitis is a common foot condition that causes pain in the heel and bottom of the foot. It occurs when the plantar fascia, a thick band of tissue connecting the heel bone to the toes, becomes inflamed. This inflammation often results from excessive strain, overuse, or improper footwear. Symptoms typically include sharp pain, especially with the first steps in the morning or after prolonged sitting. Treatment options may involve rest, stretching exercises, ice application, and supportive footwear. In some cases, physical therapy or orthotic devices may be recommended to alleviate discomfort and promote healing.
