The appearance of vesicles and fever in the throat may be due to herpes pharyngitis, which is often caused by viral infections that can cause vesicles in the throat. In addition, when the virus grows and multiplies in the body, it produces a lot of toxins, which stimulates the body’s thermoregulatory center and causes the body’s temperature to shift upward, which increases the body’s heat production and decreases heat dissipation, resulting in an increase in body temperature and the phenomenon of a blister and fever in the throat. The effect of using antiviral drugs is generally better, such as Pu Di Lan anti-inflammatory oral solution or Blue Scutellaria oral solution, the four seasons of antiviral combination, the effect is relatively good. If a viral infection occurs, it is easy to combine bacterial infections at a later stage. If bacterial infections are combined, you also need to take antibiotics at the same time for treatment, and if there is no allergy to cephalosporin, you can take cefixime for treatment. If the temperature of fever is high, above 38.5℃, it must be treated with antipyretic drugs, such as acetaminophen.
