Symptoms

Stomatitis symptoms can affect the lips and the lining inside the mouth. Symptoms include swelling, changes in tissue color, and one or more painful ulcers. The inside of the mouth may feel like it's burning. Some people may have a fever. The symptoms can lead to trouble eating, dehydration and lack of nutrition.

Treatment
