The historical priorities were rest, relief of painful arthritis, and repeated examination for carditis; modern treatment also eradicates preceding streptococcal infection and prevents recurrences. In an 1865 account, the patient would be nursed in bed, the painful anatomical joints supported, drinks and tolerable nourishment supplied, and temperature, pulse, breathing and urine observed. Moist flannel applications and opium preparations were used for severe pain and sleeplessness. Alkaline salts were commonly prescribed under a theory that the disease involved an abnormal acid material; attempts to make the urine alkaline were a therapeutic practice, not proof that an acid caused the disease. There was already disagreement about the value of specific drugs and blistering agents. A contemporary critique describes these competing treatments and stresses the inadequacy of small uncontrolled case series.^[ref]

The important complications are rheumatic carditis, including valvulitis and sometimes pericarditis, with possible heart failure; Sydenham's chorea is another manifestation. New dyspnoea, a changed heart murmur, chest pain, a pericardial friction rub, or signs of circulatory failure require reassessment rather than stronger treatment of the painful anatomical joint alone. Historically, local bleeding, Mercury and counterirritation were employed against supposed cardiac inflammation. Their historical use does not justify them now. A heart examination also matters when arthritis improves, because improvement of pain does not establish freedom from cardiac injury.^[ref]

Present management confirms the diagnosis and cardiac involvement with appropriate clinical criteria, electrocardiography and echocardiography. Penicillin or an appropriate alternative eradicates residual group A streptococci, even if the throat symptoms have resolved. An anti-inflammatory drug relieves arthritis; severe carditis, heart failure or disabling Sydenham's chorea needs specialist management. Fluid-retaining heart failure can require a diuretic with monitoring of renal function and electrolytes; treatment is selected according to haemodynamic findings. The 2025 guideline allows corticosteroids for selected severe carditis or pericarditis with effusion, under specialist care. Mild Sydenham's chorea may need only rest and a calm environment; greater functional impairment can justify carbamazepine or another carefully selected symptomatic medicine. These measures accompany, rather than replace, antibiotic prophylaxis. Secondary antibiotic prophylaxis reduces future attacks and further valve injury. Neither aspirin nor a later salicylate regimen should be presented as ordinary Oxford practice in 1865. These are historical explanations and general medical principles, not a treatment plan for an individual.^[ref]
