A peritonsillar abscess is a form of bacterial infection that originates as a complication of tonsillitis or strep throat that was left untreated. Generally, it involves the formation of a pocket filled with pus that forms close to one of the tonsils.

It is prevalent among children, teenagers and even young adults. In most cases, the abscess occurs at the start or end of the winter season when ailments such as tonsillitis and strep throat are widespread.

What are the causes?

Peritonsillar abscess typically forms as a complication of tonsillitis. In case an infection develops from a tonsil and spreads to the adjacent area, an abscess forms. This type of abscess is becoming uncommon due to the availability of antibiotics in the management of tonsillitis and strep throat.

Management

Antibiotics are generally given as treatment for a peritonsillar abscess. The doctor will drain the pus to hasten the healing by lancing the abscess to release the fluids.

If the individual could not drink or eat, intravenous fluids are given to maintain proper hydration. The doctor might also prescribe pain medications if there is significant pain.

Similar with tonsillitis and strep throat, if the abscess recurs, the doctor might suggest the removal of the tonsils to prevent future and severe infections.
