Cold sores on the lips are caused by the herpes simplex virus (HSV).
Cold sores on the lips are caused by the herpes simplex virus (HSV). Almost all adults are infected with this virus and are what is known as “carriers”. When we are sick or stressed, the virus can multiply again. Painful blisters on the lips that itch or burn are typical. Ointments from the pharmacy can provide relief.
After the initial infection, the virus remains in the body for life and sporadically causes a relapse.
The symptoms disappear on their own after two to three weeks.
