- Overview of Canker Sore
- Canker sores are round, painful sores that can be found on the inside of your cheek, tongue or the back of your throat. In many cases, they may have a red edge and a grey center. These sores are not contagious, but they can be triggered by stress, food allergy, hormonal changes, or menstrual period. Usually, these sores will subside on their own. If you are experiencing a severe case, contact your physician or make an appointment at the Student Health Services here.
