Recurrent fever in the tonsils is usually caused by bacterial or viral infections and can be treated with oral antibiotics or antiviral drugs such as penicillin. Also choose antipyretic and analgesic drugs for cooling down, such as aspirin, acetaminophen, ibuprofen, etc. In addition, rinse with mouthwash, eat a liquid or semi-liquid diet that is easy to digest and nutritious, and drink plenty of warm water. If necessary, see a surgeon for a tonsillectomy.
