The two main types of arthritis are rheumatoid arthritis and osteoarthritis. Though both affect the joints, they damage joints differently.
Rheumatoid arthritis (RA) is a disease involving the body’s immune system. The immune system attacks the synovial membrane which is the name for joint linings. If left untreated, eventually the lining, cartilage, and bone are destroyed. The typical symptoms are painful joint inflammation and swelling, to name two.
Osteoarthritis is referred to as a wear-and-tear disease. In this type of osteoarthritis, the cartilage that provides cushioning between joints deteriorates. Without the cushion, the bones grind together and eventually the connective joint tissues deteriorate. The typical symptoms of osteoarthritis are a pain when using the joint and restricted movement.
