It is possible to have both osteoarthritis and rheumatoid arthritis at the same time. For example, your knee may be affected by rheumatoid arthritis, but your spine may have degenerative changes that support the diagnosis of osteoarthritis. Rheumatoid arthritis is an autoimmune disease.
Also question is, can arthritis turn into rheumatoid arthritis?
Arthritis is an umbrella term used to describe inflammation of the joints. However, there are different kinds of arthritis, including rheumatoid arthritis (RA) and osteoarthritis (OA). Although RA and OA both affect the joints, they're very different forms of the same broader condition.
Can osteoarthritis lead to rheumatoid arthritis?
Rheumatoid arthritis (RA), an autoimmune disease, can cause osteoarthritis (OA). RA occurs when the immune system mistakenly attacks the joints causing pain and stiffness, as well as muscle pain, fatigue, weight loss and flu-like symptoms. Most people with RA are not at risk for OA.
