It is important to have children checked out if they complain of a severe sore throat. While a sore throat is a common symptom of colds, it can also indicate strep throat or tonsillitis, both of which can lead to peritonsillar abscesses. A hallmark of this sore throat caused by the latter is that it tends to appear on one side of the throat where the abscess is forming. The abscess may also be visible at the back of the throat and look like a white, swollen blister.
