Plantar fasciitis is one of the most common causes of heel pain. It involves pain and inflammation to the plantar fascia (thick band of tissue that runs across the bottom of your foot and connects your heel bone to your toes.
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 or fitness walkers who have changed their exercise regimen or developed and imbalance. In addition, people who are overweight and those who wear shoes with inadequate support have an increased risk of plantar fasciitis.
