Rheumatic fever can cause night sweats, but this symptom is not specific, as many patients with tuberculosis also experience night sweats. Rheumatic fever is a systemic inflammatory disease caused by Group A beta-hemolytic streptococcal infection. Clinically, it commonly presents with symptoms like fever, joint pain, erythema marginatum, subcutaneous nodules, chorea, and carditis. During the acute phase of rheumatic fever, if there is joint pain, non-steroidal anti-inflammatory drugs can be used for treatment. If there is carditis, corticosteroids may be administered. For patients with rheumatic fever, long-term treatment with penicillin is also recommended, typically suggested for three to five years to control the disease.
