Doctor's Notes on Rheumatic Fever
The main symptom of rheumatic fever is a fever (usually under 102 F) one to five weeks after a bout of strep throat. Other symptoms of rheumatic fever include joint swelling and pain (arthritis, often in the large joints such as knees, shoulders, and hips), heart problems (inflammation and eventual destruction of heart valves that can lead to heart failure), Sydenham's chorea (sudden involuntary movements of muscles due to irritation of specific areas of the brain), skin problems (erythema marginatum, a pink rash that looks serpentine and surrounds areas of normal looking skin), and round and painless lumps over bones such as the knees and elbows.
