Tonsillitis is the name for inflamed tonsils. You can tell tonsillitis is present when they are visible, and the throat is sore. Children can also experience fever, tenderness when swallowing, and enlarged lymph nodes on the neck. ​At-home care is usually recommended. Lots of rest, fluids, and foods that are easy to swallow. If a bacterial infection causes tonsillitis, antibiotics might be prescribed. Children who suffer from chronic tonsillitis may have them surgically removed. Your doctor will make that decision when necessary.
