Osteoarthritis (OA) Shoulder
Osteoarthritis (OA) is a common condition which can affect any joint. As part of normal life, your joints are exposed to a constant level of stress, which causes some wear and tear on the joint. In most cases, your body repairs this itself and you do not experience any symptoms but in osteoarthritis, this process becomes painful and can cause swelling and stiffness in the joint. Bony growths can develop, and the area can become inflamed (red and swollen).OA can occur at the end of the collar bone or inside the shoulder joint itself.
