Cold Sores

Cold Sores are blisters around the mouth caused by the herpes simplex virus (HSV-1). They are  contagious and can be triggered by stress, illness, or sun exposure. They are common but usually clear up on their own within 10 to 14 days. Treatment can ease discomfort, speeds up recovery and includes antiviral medications like acyclovir and over-the-counter creams to reduce symptoms.
