What are the signs and symptoms of tonsillitis or an adenoid infection?

The most prominent symptom of tonsillitis and adenoid infection is a sore throat. Other signs and symptoms of tonsillitis and adenoid infection include:

When there is a sore throat and cold symptoms such as congestion, runny nose, sneezing, and coughing, the cause is most likely a virus. Viral infection of the tonsils or adenoids usually resolves without treatment within two weeks.

Sore throat with a sudden mild fever, without symptoms of an upper respiratory tract infection, may point to a bacterial infection. If these symptoms are present, see a doctor for diagnosis because of the risk of strep throat. Although strep throat will usually go away even without treatment, an untreated strep infection can lead to complications including rheumatic fever, which can permanently damage the heart.
