As days pass, a localized skin rash usually develops, most often on one side of the body. This pattern is not accidental: the virus reactivates along a specific nerve, which explains why the lesions follow a defined path rather than spreading widely. While the visible rash draws attention, specialists emphasize that the associated pain can be the most intense and persistent symptom.
Treatment and Possible Complications
In most cases, shingles progresses favorably with proper medical treatment. Antiviral medications, when taken within the first 72 hours after symptoms begin, can shorten the course of the illness and reduce the risk of complications. However, if diagnosis is delayed, one of the most feared consequences may occur: postherpetic neuralgia—a lingering pain that can last for months or even years after the rash has healed.
