Cold Sores
Cold sores or fever blisters refere to facial lesions foudn on the area around the mouth. Cold sores usually appear on your lips. Occasionally, cold sores can be noticed on the nostrils, chin or fingers. Cold sores are painful and the swelling and redness last nearly for about 10 days. Fever sores are a reaction to the latent herpes simplex virus that is already present in the body. A person suffering from fever blisters is likely to suffer fever and headache and pain while swallowing. The cold sores may also affect the person's ability to eat. These sores later develop a yellow crust that is sloughed off to reveal new skin. Cold sores are contagious and this virus can be passed on from sharing towels or eating utensils. Prolonged exposure to sunlight may aggravate the condition of fever blisters or even bring on a recurrence. Cold sores are usually treated with anti-viral creams and cold compress. Aspirin or Ibuprufen may be taken to reduce the pain. When high fever or eye irritation is noticed, it is necessary to contact a doctor.
Shingles
Shingles (Herpes Zoster) is a viral infection caused by Varicella zoster virus. It is the same virus that causes chicken pox. Shingles can develop in anyone who has had chicken pox. The chicken pox virus often remains dormant in the body's nerve root cells. It may surface years later in the form of shingles. It is likely to occur when the body is weak or stressed or immune defences are low. Shingles is not a contagious condition nor does it lead to cold sores or genital herpes.
Shingles appear as painful blisters. Shingles rashes appear as a cluster of raised red dots on one side of the body. They become filled with fluid and later dry out and form a crust. There is severe pain and sensitivity. Typically these painful blisters appear to affect one part of the body. There may be itching and tingling feeling on the skin before the shingles rashes appear. In cases of shingles where the eye is affected, it is essential to consult an opthalmologist immediately. A patient suffering from shingles may notice fever and headache.
Calamine lotion can be applied to affected areas to soothe the skin. Analgesics or NSAIDs can help in reducing pain. Antiviral medications are often prescribed for shingles. An attack of shingles might last for about a month.
