What are the symptoms of rheumatoid arthritis? (cont.)

In rheumatoid arthritis, multiple joints are usually inflamed in a symmetrical pattern (both sides of the body affected). The small joints of both the hands and wrists are often involved. Simple tasks of daily living, such as turning door knobs and opening jars can become difficult during flares. The small joints of the feet are also commonly involved. Chronic inflammation can cause damage to body tissues, cartilage, and bone. This leads to a loss of cartilage and erosion and weakness of the bones as well as the muscles, resulting in joint deformity, destruction, and loss of function.
