Osteoarthritis (OA) is the most common type of arthritis, especially among older people. OA symptoms vary by the individual. For most people, OA can get worse over time if you don’t address the pain and symptoms now.
What is OA? Osteoarthritis mostly affects cartilage. The surface layer of cartilage
breaks down and wears away. This allows bones under the cartilage to rub
together, causing pain, swelling and loss of motion of the joint. Over time, these
changes can affect the bones, tendons, and other joint tissues.
