What's Actually Causing Your Heel Pain?

The plantar fascia is a strong band of tissue that runs along the bottom of your foot, connecting your heel to your toes. It acts like a shock absorber, supporting your arch every time you stand, walk, or run.

Over time, repeated stress can create tiny tears in this tissue. As your body tries to repair the damage, the plantar fascia can become irritated and painful. That's why many people notice a sharp pain with their first steps in the morning or after sitting for a while. As you move around, the tissue begins to loosen, and the pain may improve—only to return after a long day on your feet or after exercise.

Common Signs of Plantar Fasciitis

If you have plantar fasciitis, you may experience:

  • Sharp heel pain with your first steps in the morning
  • Pain after sitting for extended periods
  • Discomfort that improves as you walk but returns later in the day
  • Pain after exercise or prolonged standing
  • Tenderness on the bottom of the heel
  • Tightness in your arch or calf muscles
