Shingles are
characterized by excruciating pain, tingling, numbness
and a blistering rash often following the distribution
of nerves in the skin, usually on one side of the body,
or face.
Shingles - also known as postherpetic
neuralgia - is caused by the same virus that causes
chickenpox - varicella-zoster. The chickenpox virus can
remain dormant in the body only to resurface as shingles
in later years at times of extreme stress, or if the
immune system is compromised because of disease, or
during chemotherapy, or steroid treatments.
Unlike chicken pox, shingles are not contagious, however
persons with shingles can transmit the virus if the
blisters are broken and someone who has never had
chickenpox comes in contact with the fluid from the
blisters.
Antiviral drugs are used to prevent
post-herpetic neuralgia, especially in people older than
50. Most people will find pain relief with acetaminophen
or other over-the-counter pain medicines, as well as
cool compresses on the affected area. Antiviral drugs
may also help stave off the painful after-effects of
shingles if taken within 48 hours of the rash appearing.
