If you have a headache and sore throat, it may be caused by an infection. Most of them are bacterial or viral, which can be determined by simple blood tests. If it is accompanied by an increase in white blood cells and neutrophils, it is caused by bacterial infection, which requires oral antibiotics and throat-clearing medication. If it is a viral infection, you can take oral anti-viral oral solution with Chinese medicine ingredients, and drink more water to promote metabolism and pay more attention to rest. However, if the viral infection is heavy, such as influenza, accompanied by muscle pain and high fever, oral ribavirin or oseltamivir is recommended for antiviral treatment.
