What Is Calcaneal Bursitis?
Bursitis occurs as the result of an inflamed bursa. A bursa is a small fluid-filled sac which acts as a gliding surface to minimize friction between tendons, muscles, and bones. If the bursa becomes inflamed, it usually swells, loses its slippery gliding function, and becomes quite painful. Calcaneal bursitis is a type of bursitis occurring under the heel bone. Retro calcaneal bursitis and inferior calcaneal bursitis are some common types of bursitis in the heel.
