Yeah you're right- herpes simplex zoster
is the same virus as the chickenpox virus.
i'm guessing you caught it from whoever
gave you chickenpox the first time
This info is from
Penn State college of Medicine....
"Herpes Zoster is caused by the varicella
zoster virus, which also causes
chickenpox. Once you have been infected
with a form of the herpes virus, the virus
continues to live in the nerve cells of
the skin or the central nervous system,
but doesn't cause any symptoms. Something,
such as an illness, stress, sunburn, or
injury, can cause the virus to become
active again, which causes the symptoms of
HSV-1, HSV-2 or shingles. The virus may
also occur in people who are taking drugs
to suppress the immune system. Although
shingles is not contagious, someone who
hasn't had chickenpox can develop
chickenpox if they have contact with fluid
from a shingles blister. HSV-1 and HSV-2
are contagious and are spread by contact
with the fluid in the blisters."
