In this case, we consider that it is the repeated fever caused by suppurative tonsillitis. It is closely related to our incomplete treatment and inappropriate choice of antibiotics. In this case, we should give active antibiotics to treat. Antibiotics such as cephalosporins or azithromycin can be selected. It is suggested to use intravenous infusion as a treatment method to try to treat it thoroughly, so as to avoid suppurative tonsillitis at the same time of common cold. The symptoms of common cold mainly include nasal congestion, runny nose, sore throat, cough and expectoration, which are symptoms of upper respiratory tract infection. This requires us to keep warm at ordinary times and avoid getting cold, so as to avoid the possibility of suppurative tonsillitis when the body's resistance decreases. If this happens, the main thing is to insist on treatment with active antibiotics.
