Definition
Rheumatoid refers to a specific type of arthritis characterized by chronic inflammation, particularly affecting the joints. It's an autoimmune disease where the body's immune system mistakenly attacks its own tissues. Unlike osteoarthritis, which is caused by wear and tear, rheumatoid arthritis is an inflammatory condition. Think of it as the body waging war against itself within the joints. It results in pain, swelling, stiffness, and potentially joint damage over time. This condition requires medical intervention.
