There are a couple situations where your swollen feet, ankles and legs are not a cause for concern. If you just spent the last eight hours on your feet or if you are pregnant, you might expect your lower extremities to swell from time to time.
One of the most common causes of pain in the heel of the foot is plantar fasciitis (Plan-tur Fas-e-I-tis). The plantar fascia is a thick band of tissues that is located on the bottom of the foot, connecting the heel bone to the toes. When this band of tissues becomes irritated and inflamed it is known as the plantar fasciitis.
