What is Rheumatoid Arthritis?
Arthritis is a general term that means inflammation in a joint. Joint inflammation is characterized by redness, warmth, swelling, and pain within the joint.
Rheumatoid arthritis is a type of chronic arthritis that typically occurs in joints on both sides of the body (such as hands, wrists, or knees). This symmetry helps distinguish rheumatoid arthritis from other types of arthritis.
In addition to affecting the joints, rheumatoid arthritis may occasionally affect the skin, eyes, lungs, heart, blood, or nerves.
