Patients with rheumatoid arthritis can safely consume millet porridge, as it is highly nutritious and does not affect rheumatoid arthritis. Rheumatoid arthritis is somewhat associated with streptococcal infections, and clinically it mainly presents as migratory pain in the major joints of the limbs. With the widespread use of penicillin in recent years, the incidence of rheumatoid arthritis has become increasingly low. Nowadays, it is occasionally seen in clinical practice, mainly among patients with repeated streptococcal infections, such as those with recurrent tonsillitis, who may experience episodes of rheumatoid arthritis. In such cases, removing the cause can generally achieve clinical cure. Nonsteroidal anti-inflammatory drugs and penicillin antibiotics can be used to treat acute episodes.
