Rheumatoid arthritis

Rheumatoid arthritis is an allergic disease and is one of the main manifestations of rheumatic fever. It usually starts with acute fever and joint pain. The typical manifestations are mild or moderate fever, migratory polyarthritis, and the affected joints are usually large joints such as knee, ankle, shoulder, elbow, and wrist. In the other joint, the lesion was locally red, swollen, burning, and severely painful. Some patients also developed several joints at the same time. Atypical patients had joint pain but no other inflammation. Acute inflammation usually subsided in 2-4 weeks. Sequelae, but often recurrent. If rheumatism affects the heart, myocarditis can occur and even heart valve disease can remain.
