What is Herpes zoster?

Condition analysis:
Herpes zoster (commonly referred to as "shingles") and postherpetic neuralgia result from reactivation of the varicella-zoster virus acquired during the primary varicella infection, or chickenpox. Whereas varicella is generally a disease of childhood, herpes zoster and post-herpetic neuralgia become more common with increasing age.

Factors that decrease immune function, such as human immunodeficiency virus infection, chemotherapy, malignancies and chronic corticosteroid use, may also increase the risk of developing herpes zoster.

The skin lesions begin as a maculopapular rash that follows a dermatomal distribution, commonly referred to as a "belt-like pattern." The maculopapular rash evolves into vesicles with an erythematous base (reddish base). The vesicles (generally fluid filled eruptions) flare, these are generally painful, and their development is often associated with the occurrence of anxiety and flu-like symptoms.

Reactivation of latent varicella-zoster virus from (nervous system in fact spinal cord extension of brain from where nerves arise) dorsal root ganglia is responsible for the classic dermatomal rash and pain that occur with herpes zoster. Burning pain typically precedes the rash by several days and can persist for several months after the rash resolves.

Instructions:
1. Use a wet compress
Just like the bath, anything cool and wet will feel great on your skin. Just grab a washcloth, soak it in cool water, wring it out, and apply to your skin. After several minutes, repeat the process to renew the feeling.

-- Don't use ice packs! Those are too cold for your skin right now -- if you think it's sensitive normally, it's extra sensitive right now.
-- Always, always, always wash your towels after you use them, especially when you have shingles.

2. Use calamine lotion
Normal lotions -- especially those that are scented -- could just make the situation worse. Stick to lotions like calamine that are extra soothing and be sure to wash your hands after application. Remember to apply it only to the affected area.
