RA & OA

Rheumatoid Arthritis (RA) IS AN AUTOIMMUNE DISEASE

• Rheumatoid arthritis (RA) is not a condition of wear and tear. It is a disease in which your own immune system mistakenly attacks healthy tissue, causing inflammation that damages your joints.
• RA usually causes pain or stiffness lasting for more than 30 minutes in the morning or after long rest and lack of activity.
• RA can occur at any age. It often begins in middle age and tends to get worse over time.
• RA is associated with symmetrical swelling (e.g., both hands, both elbows, etc.)
• Most typically, RA symptoms include joint pain, swelling, tenderness, and redness of the joints; prolonged morning stiffness; and less range of movement. Some people also experience fever, weight loss, fatigue, and/or anemia.
• With RA, inflammation generally occurs in the knuckles and at the joints closest to your hands, nearer the base of your fingers.
• RA tends to cause swelling and pain in smaller joints such as the hands and ankles.

Osteoarthritis (OA) IS A CONDITION OF WEAR AND TEAR

• OA is not an autoimmune disease. It is a condition of wear and tear associated with aging or injury. Your immune system is not affected.
• OA stiffness tends to get worse with use throughout the day.
• OA usually occurs as individuals age and in those whose joints have become worn down by excessive use.
• Generally, OA symptoms include joint stiffness, pain, and enlarged joints.
• OA is associated with asymmetrical (not "matching") swelling in individual joints that are not part of a pair — e.g., one knee and an elbow, instead of both knees.
• With OA, inflammation generally occurs at the joint closest to your fingernail.
• OA tends to cause pain and swelling in bigger joints such as the hips and knees.
• OA is much more common than RA. In the United States alone, an estimated 20 million people have osteoarthritis, and approximately 2.1 million people have RA.
