Cold sore

A cold sore is a skin lesion on the lips caused by infection with the herpes simplex virus (HSV). Cold sores are extremely common. In fact, most adults are infected with HSV, usually transmitted in childhood by normal close contact with parents, siblings or friends.

While the infection can be entirely unnoticed, or asymptomatic, the cold sores themselves are usually visible and sometimes painful. In an otherwise healthy individual, they are essentially harmless, though their appearance can cause a great deal of distress.

As with most viruses, there is no cure for HSV infection, though certain medications can decrease the rate of outbreaks for those who are severely afflicted.

Mouth and throat sores from cancer treatment

Mouth sores are a common side effect of cancer treatment (chemotherapy or radiation therapy). Some types of chemotherapy are more likely to cause this than others. Cancer treatments are used to kill the bad cancerous cells, but unfortunately they also affect healthy cells. The cells of the inner lining of your mouth, esophagus (the tube that carries food from the mouth to stomach) and stomach can get damaged too. This can result in symptoms like red areas or a burning feeling in the mouth, painful sores and painful or difficulty swallowing.
