For this reason it is wise to avoid exposure of chicken pox to the elderly or immune weak. Zoster virus which causes chicken pox also causes shingles. Shingles is a very painful viral infection of the nerve endings. It usually starts out as shooting pain and after several days a rash appears along the line of the nerve. It can last anywhere from several weeks, to months, to years.
Most people get shingles in the torso.
It is suggested that if shingles appear on the face to see an Ophthalmologist to prevent spreading to the eyes which can cause blindness. In one case the shingles disappeared in a few days. Zoster virus is around all year, it seems to thrive in the fall to wintertime of the year. It is virtually impossible to avoid the virus, but the healthier your immune system is the less likely it will get out of hand. I only believe in intervening even herbally if the child's immune system seems not to be able to handle it.
