J03.9: Acute tonsillitis, unspecified

Your tonsils are inflamed.

The palate is the roof of the mouth. The front of the palate consists of a bone plate, the hard palate. At the rear, the palate transitions into the soft palate. At the back of the palate, in the middle, hangs the uvula. To the side of this are the palatine arches. The tonsils are on the left and right between the palatal arches. The tonsils are part of the immune system.

An inflammation of the tonsils is also called tonsillitis. If you have tonsillitis, your throat will be sore and you will have difficulty swallowing. A high temperature is also common.
