Rheumatoid arthritis (RA) is a chronic inflammatory disorder that significantly impacts various body systems, including joints, skin, eyes, lungs, heart, and blood vessels. This autoimmune disorder causes the immune system to mistakenly attack healthy cells, leading to inflammation and painful swelling, particularly in the hands, feet, and joints. RA is known for affecting multiple joints simultaneously, commonly those in the hands, wrists, and knees.
The damage caused by RA primarily affects the lining and cartilage of the joints, leading to swelling, which is a common symptom of the disorder. Swelling in RA can result in pain and permanent damage, making early treatment crucial for managing symptoms and preventing long-term complications.
Inflammation from RA can cause discomfort and, if not adequately managed, lead to significant damage to the body. Understanding why swelling occurs and how to effectively relieve it is essential for those dealing with RA. Updated information from September 7, 2023, highlights the importance of addressing this symptom for better quality of life.
Rheumatoid Arthritis (RA) Symptoms and Complications, as medically reviewed by David Zelman, MD, and contributed by WebMD Editorial Contributors, emphasize that RA symptoms primarily affect joints. Additionally, RA can sometimes present as “flares,” where systemic symptoms increase, including joint swelling or tenderness. Fever is another occasional symptom, usually low grade (37 to 38°C, 99 to 100°F).
