Question

How long after vaccination can you get a fever needle?

Answer

In your case, it is recommended to first use alcohol wipe bathing to lower body temperature, then find out the cause of the fever. There are many reasons for fever, the most common being infection, followed by connective tissue disease, malignant tumors, and others. It is not advisable to rush into using medication without determining the cause. If the symptoms you describe are considered tonsillitis, which falls under upper respiratory tract infection, treatment is mainly with antibiotics. Consider intravenous injection therapy, or you can try boiling five lanterns in water for drinking, which may be more effective.
