Shingles or herpes zoster, is an adult reactivation of a
childhood chickenpox infection - a painful, blistered rash that
can develop only in people who have had chickenpox at some point
in their lives. Unlike chickenpox though, the shingles rash only
appears on a small part of the body, often in rows - similar to
tiles on a roof.
Shingles affects both sexes equally with about two-thirds of
cases occurring in those over the age of sixty.
A shingles attack may begin with a fever, combined with
chills, headaches and an upset stomach. The patient may also
complain of an itching or burning sensation a few days prior to
the rash - this occasionally being mistaken for other problems
i.e. back problems, lung infection or a heart attack.
The shingles rash starts as a series of raised red spots that
develop into clear blisters that dry out, eventually forming a
crust. A swollen area surrounds the spots, which may bleed and
become extremely itchy and painful. Once the rash fades (usually
after 3-4 weeks) the area usually stops hurting and full
recovery follows. It is possible for the pain to persist for
months, if not years afterwards, this is known as post-herpetic
neuralgia. Whitish-silver or brownish scars usually remain as a
result of the blisters.
The herpes zoster virus is responsible for both chickenpox in
childhood and shingles in adulthood. This virus belonging to the
same family as the herpes simplex organism, responsible for cold
sores/fever blisters. But while chickenpox is highly contagious,
shingles is not generally passed on from one individual to
another. Except when those who have not yet had chickenpox touch
moist shingle blisters.
Shingles occurring on the face, cornea of the eye or ears
(zoster keratitis) is often more serious, as it can cause
blindness if left untreated. Seek medical attention immediately!
Treatment
- Antiviral drugs will shorten the course of the illness and
reduce the risk of post-herpetic neuralgia if diagnosed early
and treatment beginning within 24 hours of the rash appearing.
- If the rash has affected the forehead, special eyedrops
will be prescribed to protect the eyesight.
- Three drops each of the essential oils, geranium, sage and
thyme blended in 20ml of carrier oil can be applied to the
affected area.
- The patient should wear loose clothing to prevent the
blisters from being rubbed and irritated.
- Frequent cool baths may also help relieve the pain.
