Tonsils and Tonsillitis
Tonsils are clumps of tissue on both sides of the throat that help fight infections.
Tonsils may swell when they become infected (tonsillitis). If you look down your child's throat with a flashlight, the tonsils may be red and swollen or have a white or yellow coating on them. Other symptoms of tonsillitis can include:
pain or discomfort when swallowing
swollen glands (lymph nodes) in the neck
Enlarged tonsils without any symptoms are common among kids. Left alone, enlarged tonsils may eventually shrink on their own over the course of several years.
Don't rely on your own guesses, though — it can be hard to judge whether tonsils are infected. If you suspect tonsillitis, contact your doctor. Recurrent sore throats and infections should also be evaluated by the doctor, who may order a throat culture to check for strep throat.
