Plantar fasciitis is the most common causes of heel pain. It involves inflammation of the thick band of tissue that runs across the bottom of your foot and connects your heel bone to your toes.
Plantar Fasciitis causes stabbing pain that usually occurs with your first steps in the morning. As you get up and move, the pain normally decresses, but it might return after long periods of standing.
Plantar fasciitis is more common in runners. People who are overweight and those who wear shoes with inadequate support also have an increased risk of plantar fasciitis.
