Conception
Herpes zoster,
otherwise known as shingles, is an infection of the nerves
that supply certain areas of the skin. The condition is
characterized by a cluster of painful vesicular eruptions.
In Chinese medicine, it is known as Che Chuan Chuang
(snake cluster sores). According to western medicine, herpes
zoster is caused by the varicella-zoster virus.
Signs and
symptoms
Prodromal
symptoms of chills and fever, malaise and poor appetite may
occur for about 3-4 days before the classic skin lesion
appears. A burning sensation and pain occurs along the site
of the future skin lesion. On about the fourth or fifth day,
characteristic clusters of vesicles on an erythematous base
appear. The cutaneous distribution follows the route of the
affected nerve(s) and the associated pain may be severe. The
skin lesion occurs most often in the thoracic, abdominal and
loin regions and spreads unilaterally. The serous fluid in
the vesicles is initially clear, but then becomes cloudy 4-5
days later. The vesicles begin to dry and scab on about the
fifth day after appearance. Other areas that may be affected
by herpes zoster include the face, eyes, chest, and the
medial side of the upper legs. An attack of herpes zoster
usually confers immunity; recurrence is rare. Post herpetic
pain may persist for months or even years, especially in
older people. The whole course usually lasts about two
weeks, and less than one month.
Differential
diagnosis
Diagnosis may
be difficult in the early stage, but is made easily after
the vesicles appear in the characteristic distribution along
sensory nerve pathways. Pain is also an outstanding feature
of herpes zoster, especially post-zoster pain.
If the pain is
in the thoracic and abdominal region, it must be
differentiated from that of gallstones, colitis,
appendicitis and renal colic.
Herpes simplex
lesions may be nearly identical to those of herpes zoster.
Herpes simplex generally recurs, whereas zoster rarely does.
Contact
dermatitis can also present erythematous skin lesions with
vesicles, but it will have a history if skin contact with an
offending substance, and generally there is no associated
pain.
Traditional
Chinese Medicine Etiology
The main cause
of herpes zoster is fire and toxin in the liver meridian.
Spleen deficiency with dysfunction of transportation and
transformation resulting in damp heat is also a common cause
of herpes zoster.
In aged people,
weakness of the body, blood deficiency, liver yang excess or
fatigue, toxic factors invading the body, excessive
damp-heat toxin, and qi and blood stagnation facilitate the
occurrence of the skin lesions.
