The symptoms of rheumatic arthritis, such as joint swelling and pain, generally improve on their own within about two weeks, with the longest duration not exceeding one month. However, since rheumatic arthritis is triggered by a Streptococcus infection, if the Streptococcus infection is not actively controlled, it is easy for the arthritis to relapse after the joint pain has improved. Therefore, for patients with rheumatic arthritis, it is essential to treat the Streptococcus infection early. Treatment with second-generation cephalosporin antibiotics for 10-14 days is recommended, followed by regular long-acting benzathine penicillin treatment at outpatient clinics to achieve a complete cure of rheumatic arthritis. (Specific medications should be used under the guidance of a doctor.)
