Hi!
welcome to HCM!
Shingles is the infection caused by varicella-
zoster virus — the same virus that causes
chickenpox. After having chickenpox, the virus lies inactive in nerve tissue near your
spinal cord and brain. Years later, the virus may reactivate as shingles.
While it isn't a life-threatening condition, shingles can be very painful.
Treatment with
antiviral drugs is required only if the pain and rash occur near an eye to prevent permanent eye damage.
You're 65 or older, which increases your risk of complications.
You have a weakened immune system .
The rash is widespread and very painful.
Vaccination will not be useful now after the infection has already occured and subsided.
hope this will help you!take care!
