Cold sores keep coming back recently. i haven't changed my diet or anything so what is the problem?

A doctor has provided 1 answer

Stress?: Stress in the form of emotional or physical stress can cause cold sores to recur. Sun exposure causes it in some people as well. You can take medication daily to suppress the herpes virus. See your doctor about this.
