Bursitis
We all have hundred’s of bursa throughout our bodies, the function of which is to decrease friction between two surfaces that move in different directions. Bursa are found at points where muscles and tendons glide over bones and without them, movement would be painful. Bursitis is the inflammation of a bursa which comes about from muscles or tendons pulling at the wrong time, too hard or from the wrong angle. This is commonly seen in repetitive movements but can occur through minor impact or by a sudden, more serious injury.
