Herpes zoster, commonly known as shingles, is a condition

where early treatment is absolutely crucial.

Caused by the reactivation of the varicella-zoster virus—

the same virus responsible for chickenpox—shingles often

begins quietly. Many people first notice tingling, burning, itching,

or sharp pain on one side of the body or face days before a rash appears.

Because these early symptoms can feel vague or unrelated,

the disease is frequently overlooked during its most treatable stage.
