It is easier to prevent nausea than treat it once it has occurred. Follow antinausea drug directions closely. Drink plenty of liquids. Eat often in small amounts. Sore mouth may occur a few days after treatment.
Mouth sores can occur on the tongue, the sides of the mouth or in the throat.
Mouth sores or bleeding gums can lead to an infection. Brush your teeth gently with a very soft toothbrush. If your gums bleed, use gauze or your finger instead of a brush. Make a mouthwash with teaspoon baking soda or salt in 1 cup warm water and rinse several times a day. Try chilled or frozen yogurt and soft, bland food.
