Rheumatoid Arthritis (RA) is a chronic autoimmune disorder where the body's immune system mistakenly attacks its own joints, causing inflammation, pain, and potential damage to other organs. Early symptoms often include symmetric joint stiffness (especially in the morning), pain in the hands, wrists, and feet, and fatigue. As it advances, it can lead to joint deformities, constant pain, and complications in the heart, lungs, or eyes. Modern treatment focuses on early, aggressive management using Disease-Modifying Antirheumatic Drugs (DMARDs) like Methotrexate and advanced biologics to suppress the immune system and prevent joint erosion. You should consult a Rheumatologist at a hospital known for its orthopedics and rheumatology department. To manage flare-ups, rest the affected joints, use anti-inflammatory medications as prescribed, and apply warm or cold compresses. Long-term treatment costs are substantial, often ranging from $2,000 to $5,000 or more annually for medications and regular monitoring, making good health insurance essential.
