Plantar fasciitis is a very common condition in people who walk or run a great deal, particularly on hard surfaces. In this video, Dr. Johanna Youner, board-certified podiatric surgeon and a Fellow of the American College of Foot and Ankle Surgeons, explains what plantar fasciitis is, what causes it, how to prevent and how to treat it. Plantar fasciitis, inflammation of the foot ligament that attaches to the heel, causes significant pain in the heel area, especially right after getting out of bed in the morning. If you experience such pain, get shoes with more support. If the pain has been an ongoing problem, see a podiatrist—the condition can worsen if left untreated.
