A Broad Term Covering Many Conditions
Arthritis is a broad term for a group of conditions that affect the joints and can cause pain, stiffness, swelling and reduced movement. There are many different types of arthritis, including osteoarthritis and rheumatoid arthritis. Rheumatoid arthritis is an autoimmune condition in which the immune system attacks the tissues lining the joints, causing inflammation and potentially affecting other parts of the body. The effect of arthritis on your ability to work can depend on the type of condition, which joints are affected, the severity of symptoms and how those symptoms affect your ability to perform and sustain your usual work.
