What is plantar fasciitis?

The plantar fascia (say: PLAN-tar FASH-ee-ah) is a band of tough fiber on the bottom of your foot (see drawing). It runs from your toes to your heel and forms the arch of your foot. When this tissue becomes hot, red, swollen, and sore, it is called plantar fasciitis (say: fash-ee-EYE-tis). Plantar fasciitis makes your heel hurt when you walk. The pain is usually worse when you get out of bed in the morning or when you walk after sitting for a long time. Walking barefoot, walking on tiptoe, or walking up stairs may make the pain worse.

Who gets plantar fasciitis?

About 10 percent of people have plantar fasciitis. People who spend most of the day on their feet, who are overweight, and who cannot move their feet and ankles very well are more likely to get plantar fasciitis. If you become more active than usual too fast, you may get plantar fasciitis.

How do I know if I have plantar fasciitis?
