Shingles (herpes zoster) is a nerve infection caused by the chicken-pox virus. Shingles results from reactivation of the chicken-pox virus that remained in your body since you had chicken pox--perhaps many years ago. Herpes zoster (shingles) is caused by the chicken-pox virus. The rash of shingles begins as red patches that soon develop blisters, often on one side of the body. The blisters may remain small or can become large. They heal in two to four weeks. They may leave scars. Shingles is often painful, this is because the virus travels along the nerve to get to the skin resulting in inflammation and damage to the nerve. To treat:
Acyclovir helps to control the skin eruption. It is not a cure, but helps to heal the rash, provided treatment is started early. Acyclovir is taken by mouth.
Even taking acyclovir may not eliminate discomfort, burning sensations, or pain. If the discomfort is mild, take Tylenol or a similar mild painkiller.
If you have too much pain, we can order a prescription painkiller to take until the pain subsides. The pain is caused by inflammation of a nerve. Cortisone taken by mouth is sometimes used in treating the nerve inflammation.
The blistering rash usually clears in a few weeks. The discomfort may persist longer.
Treat your rash gently. Don't open your blisters. As long as there is blistering or crusting, compresses with dilute vinegar will make you more comfortable. Compress the blisters or crusts for 10 minutes twice daily with a mixture of one-quarter cup of white vinegar and two quarts of lukewarm water. Stop the compresses when the blisters have dried up.
Later, when the crusts and scabs are separating, your skin may become dry, tense, and cracked. If that happens, rub on a small amount of white petrolatum (plain Vaseline) three or four times a day.
