Plantar fasciitis is one of the most common orthopedic conditions relating to the foot. It occurs when the thick tissue on the bottom of the foot (the plantar fascia) becomes inflamed and irritated, making it difficult to walk. This is most often the result of repeated episodes of minor but recurring injury, such as with frequent running or long periods of standing. The pain can be located in the heel area of the foot or in the arch. It is often worse in the morning due to stiffness of the tissue, becoming more painful after long periods of walking. This pain often decreases with rest.
A heel spur is an extension of the heel bone that extends into the tissue directly in front of the heel. It is most often a result of chronic plantar fasciitis.
