Rheumatic fever is not effectively treated by applying a towel. It is a systemic inflammatory disease caused by an infection of group A beta-hemolytic streptococcus. Clinically, common manifestations include fever, erythema marginatum, subcutaneous nodules, joint pain or arthritis, chorea, and carditis. The heart involvement primarily affects the valves, with the mitral and tricuspid valves being the most commonly affected, leaving many patients with valvular vegetations. The incidence of rheumatic fever has become relatively rare, mainly due to the widespread use of penicillin in recent years. During the acute phase of rheumatic fever, if joint pain occurs, non-steroidal anti-inflammatory drugs such as etoricoxib or meloxicam can be used for treatment.
