The goal of every
cold sore
treatment is to make sure that those sore and unsightly
blisters are
absent a lot more than they are present.
Cold sores are caused by Herpes Simplex virus, usually Herpes Simplex type1. Genital herpes is caused in 70-80% by Herpes Simplex virus type2. The virus itself lives in nerve endings. Nearly all of us carry the cold sore virus even when it's not causing symptoms. This means that millions of people are infected with the virus, but probably only a quarter of those infected have symptoms of any kind.
A rise in
skin temperature - perhaps caused by fever or to much sunlight -
activates
the virus and they spread out from the nerve endings. That's why cold
sore is often called fever
blister. A local or general weakening of the
immune system is needed for an outbreak.
Physical or mental stress
Excessive cold or heat, including fever
Exposure to strong sunlight
Menstruation
Local skin trauma
A tingling sensation (itching and irritation) around the mouth heralds the sore's imminent arrival, usually within a day or two.
The skin feels oversensitive to touch.
Raised, swollen red area usually around the nostrils and lips.
Tiny blisters form on the spot.
Blisters enlarge, burst, oozes fluid and become painful ulcers after 2 or 3 days.
The ulcers crust over, form scabs. They may crack and bleed easily.
As you would
expect, herpes is highly contagious. There is 90% chance of catching it
if a member of the family has an active blister. The virus is
transmitted through skin contact, for example kissing.
Cold
sore that develops near
the eye is potentially dangerous and should be
seen by a doctor, as soon as symptoms, such as tingling or itching,
begin.
As you can see, cold sores are not only
annoying they can also be dangerous, so the cold sore treatment has a
great importance.
