How can we detect aphthae?
Before an aphtha appears, you may feel itchiness or a tingling sensation in your mouth. When the sore has already appeared it may be painful, and bothersome when you speak, eat or drink.
To have aphthae is no excuse to miss school. Usually they are small, and not so terribly painful to prevent you from doing anything. Therefore, one must be patient, and wait for them to go away. For a few days, the aphtha will go with you everywhere.
