Pain from chemotherapy

Mouth sores

Mouth sores

Painful sores in the mouth and throat (called mucositis and stomatitis) are caused by many types of chemotherapy, and are especially common in patients undergoing both chemotherapy and radiation therapy.

This pain can be severe and can even interfere with your ability to eat and drink. Treatment may include pain-relieving medications as well as numbing medicine (topical anesthetics) applied directly on the sores.

It may be helpful to keep the lips well lubricated with petroleum jelly or lip balm, and avoid foods that are rough, salty or acidic (like vinegar, tomatoes and citrus fruits).

Gentle cleaning of the inside of the mouth with mouth wash or special swabs may also be soothing. Ask your doctor or nurse for specific recommendations.
