Rheumatoid arthritis is an autoimmune disease. The immune system mistakenly attacks joint lining and can also affect other parts of the body.
Common symptoms
Symptoms can include joint pain, swelling, warmth, morning stiffness, fatigue, and reduced movement. It often affects hands, wrists, and feet on both sides of the body.
Why early care matters
Ongoing inflammation can damage joints over time. Early diagnosis and medical follow-up can help reduce damage and manage symptoms.
Rheumatoid arthritis is different from osteoarthritis because it is driven by immune inflammation, not only joint tissue changes from age or use.
