Rheumatoid Arthritis (RA) is a chronic autoimmune disease that causes inflammation in the joints and surrounding tissues. Unlike osteoarthritis, which is caused by wear and tear on the joints, RA occurs when the body's immune system mistakenly attacks healthy joint tissue, leading to pain, swelling, and progressive joint damage. RA can also affect other organs and systems, such as the skin, eyes, lungs, and heart. Symptoms of RA typically include joint pain and swelling, especially in the hands and feet, fatigue, and fever. The exact cause of RA is unknown, but a combination of genetic and environmental factors is thought to play a role. RA is a long-term condition that can be managed with medication, physical therapy, and lifestyle changes.
