Cold Sores: Blisters
built 793 days ago
While Cold sores... known as fever blisters, are caused by the highly contagious herpes simplex virus. The virus attacks the skin and mucous membrane, producing painful blisters around the mouth and nose. Cold sore symptoms usually start with a tingling sensation, which may advance to a painful burning or itching feeling. This stage is known as the prodromal stage. A small reddened area then develops followed by formation of fluid-filled blisters. Because these blisters form in a cluster, two or more may join to form a larger blister.

Cold sores should not be confused with canker sores, which are small ulcerations in the mouth. The blisters, which are contagious, later break, ooze, and crust over before healing. Recurrences are common and can be triggered by stress, sun exposure, illness, and menstruation. Genital herpes infection (usually caused by herpes simplex 2) is a related condition and potentially may be treated in much the same way as herpes simplex 1.

Cold sores are caused by a viral infection that attacks the skin and nervous system. They are small, painful, fluid-filled blisters on the mouth or nose. Cold Sores are a common condition. Some estimates indicate that over 80% of the population will suffer from a cold sore (herpes simplex 1) sometime in their life.

Cold sores may appear with colds, fevers, exposure to excessive sunlight, or menstrual periods, as well as during periods of stress or illness. The sores usually disappear within two weeks. Initially, there may be tingling or prickling at the site of the cold sores even before they are visible (called the prodrome); afterward, the blisters often weep a clear fluid and form a scab. If the infection is transmitted to the eyes, it may lead to blindness.
