Inflammation of the tonsils with fever recurs for no more than a week, usually for up to 5 days. It is related to the severity of the tonsils on the one hand, and the patient’s personal health on the other. When tonsillitis is severe, it may cause other complications if not taken seriously, so treatment measures should be taken actively. Through medication, oral antibiotics such as cephalosporin and penicillin can be taken, and anti-inflammatory and analgesic drugs such as ibuprofen can also be taken orally to control fever, and when a peri-tonsillar abscess develops, it needs to be incised and drained to avoid recurrent episodes of low-grade fever. Adopt good personal habits and eat a light diet to avoid worsening of the condition. If the tonsil inflammation and fever recur for a long time, you should consult a doctor to receive regular treatment. The medication should be used according to the doctor’s prescription.
