oh okay thanks i'll be on the look out for another cold sore... but what if it never comes back again? does that mean it can possibly be something else? i heard that angular cheilitis is often mistaken for a cold sore and they can blister/scab too mostly in the corners. sorry the picture might not be as accurate but i tried my best to draw it. it was so close to the corner that my mouth would crack if i open it. & i was wonder why i didn't get any herpes on my penis after the day i touched it and masturbated it's been 2 weeks and 5 days now.
Hi,
The picture that you have sent shows the marked area to be a common site for the cold sore to occur.
Cold sores, also called fever blisters, are groups of small blisters on the lip and around the mouth. The herpes simplex virus usually enters the body through a break in the skin around or inside the mouth.
Do you recall being in close proximity with an infected person? It is usually spread when a person touches a cold sore or touches infected fluid-such as from sharing eating utensils or razors, kissing an infected person, or touching that person's saliva.
The skin around the blisters is often red, swollen, and sore. The blisters may break open, leak a clear fluid, and then scab over after a few days. They usually heal after several days to 2 weeks. Small children sometimes drool before cold sores appear. This fits in with what you have described.
The herpes simplex virus that causes cold sores cannot be cured. After you get infected, the virus stays in your body for the rest of your life. If you get cold sores often, treatment can reduce the number of cold sores you get and how severe they are.
You can avoid the things that trigger your cold sores, such as stress and colds or the flu. Always use lip balm and sunscreen on your face. Too much sunlight can cause cold sores to flare.
The only way of knowing whether it was one, for sure, is if you get another one later on, without being in contact with an infected individual.
