Symptoms of plantar fasciitis can occur suddenly or gradually. When they occur suddenly, there is usually intense heel pain on taking the first morning steps, known as first-step pain. This heel pain will often subside as you begin to walk around, but it may return in the late afternoon or evening. When symptoms occur gradually, a more long-lasting form of heel pain will cause you to shorten your stride while running or walking. You also may shift your weight toward the front of the foot, away from the heel.
