What causes Tonsillitis?
The tonsils are lymph nodes in the back of the mouth and top of the throat. They normally help to filter out bacteria and other microorganisms to prevent infection in the body.
They may become so overwhelmed by bacterial or viral infection that they swell and become inflamed, causing tonsillitis. The infection may also be present in the throat and surrounding areas, causing inflammation of the pharynx. The pharynx is in the back of the throat, between the tonsils and the voicebox (larynx).
Tonsillitis is extremely common, particularly in children.
Who is at risk for Tonsillitis?
How do I know I have Tonsillitis?
The health care provider will look in the mouth and throat for swollen tonsils. The tonsils are usually reddened and may have white spots on them. The lymph nodes in the jaw and neck may be swollen and tender to the touch.
