Overview

Plantar fasciitis (PLAN-tur fas-e-I-tis) is one of the most common causes of heel pain. It involves inflammation of a thick band of tissue that runs across the bottom of your foot and connects your heel bone to your toes (plantar fascia).

Plantar fasciitis commonly causes stabbing pain that usually occurs with your first steps in the morning. As you get up and move more, the pain normally decreases, but it might return after long periods of standing or after rising from sitting.

Plantar fasciitis is more common in runners. In addition, people who are overweight and those who wear shoes with inadequate support have an increased risk of plantar fasciitis.
