Rheumatic fever clinical symptoms
The clinical manifestations of rheumatic fever primarily include: Some patients may experience low fever and rashes, and about half of the patients may exhibit symptoms such as morning stiffness. The joint pain associated with rheumatic fever often occurs more frequently in the large joints of the lower limbs and is asymmetrical, but it can also affect small joints and central axis joints. It commonly presents as non-migratory arthritis. Secondly, patients with rheumatic fever may experience cardiac involvement, with the most common being heart valve disease, particularly mitral valve stenosis. Additionally, patients with rheumatic fever may also suffer from kidney involvement, often presenting with symptoms such as hematuria and proteinuria, which are typical clinical symptoms of rheumatism.
