Heel Pain That Appears Suddenly? One Small Symptom Could Have Several Different Causes

One of the most common causes of this symptom is plantar fasciitis—a condition where the band of tissue connecting your heel to your toes becomes inflamed. This tissue, called the plantar fascia, helps support the arch of your foot. When it is overused or strained, tiny tears can develop, leading to pain and stiffness, especially after periods of rest like sleep.

Morning heel pain happens because, overnight, the plantar fascia tightens. When you take your first steps, it suddenly stretches, causing that familiar sharp or stabbing sensation. The pain may decrease as you move around, but it can return after long periods of sitting or inactivity.
