RA (Rheumatoid Arthritis)

Rheumatoid arthritis (RA) is a chronic autoimmune disorder where the immune system mistakenly attacks the joints’ lining, causing inflammation. This leads to pain, swelling, stiffness, and often joint damage over time. RA typically affects multiple joints symmetrically, such as both hands or knees, and can also impact organs and other tissues. It is a persistent condition that fluctuates in severity, and early diagnosis and treatment are crucial to control symptoms and prevent long-term damage. RA is different from osteoarthritis, which is caused by wear and tear, as it involves immune system dysfunction.
