Arthritis is not a Single Disease

Confusions might arise when people talk about arthritis without proper knowledge. It is because not many people know that arthritis is not a single disease. It actually refers to a group of more than 100 rheumatic diseases and other conditions, causing pain, stiffness, and inflammation in the joints. Arthritis is often associated with inflammation of one or more joints, but actually it can also cause inflammation and pain in any part of your body. Some forms of arthritis are classified as systemic because they can affect the whole body. It may affect the muscles, bones, and other internal organs. The joints most often affected are: knees, hands, hips, and spine.
