What causes blisters on the tonsils?


Blisters on the tonsils are caused by infections, according to Net Doctor. Kids Health explains that the coxsackievirus causes small blisters to develop not only on the tonsils, but also on the roof of the mouth. After several days, the blisters erupt, and the area scabs over.

Coxsackievirus is the virus that causes hand, foot and mouth disease. Not only does this viral infection cause painful red blisters to develop on the tongue, throat and hard palate, it can also cause blisters to form on the insides of the cheek, soles of the feet and palms of the hands, according to Kids Health. Herpangina, a viral throat infection, is also caused by the coxsackievirus, and causes ulcers and red-ringed blisters to form on the tonsils, roof of the mouth and the soft palate. While bacterial infections are usually treated with antibiotics, coxsackievirus is a viral infection and does not respond to antibiotic therapy. While the coxsackievirus can occur anytime, it is most common in the late summer and early fall, according to the New York Times. Coxsackieviruses are part of the enterovirus family, other members of which are responsible for causing hepatitis A and polio. Coxsackieviruses are easily spread from person to person, and typically go away without any treatment.
