(HealthDay News) -- Tonsils, pink tissue on both sides of the throat, can become infected and inflamed in some people, a condition called tonsillitis.

Here are some signs of tonsillitis, courtesy of the American Academy of Pediatrics:

• Red or swollen tonsils.
• A hoarse voice.
• Yellow or white coating on the tonsils.
• A sore throat.
• Pain swallowing.
• Swollen glands
• A fever.

Parents can see the tonsils by looking at the back of the child's throat with a flashlight. In some cases, the tonsils may have to be removed.
