In many cases, the first symptoms are nonspecific and can be confused with other health problems. Localized pain, burning, tingling, or hypersensitivity in a specific area of the body are often the first indications. These discomforts can appear days before the visible manifestations emerge, making early diagnosis difficult if they are not monitored.
As the days pass, a localized rash usually appears, generally on only one side of the body. This pattern is not random: the virus reactivates along a specific nerve, which explains why the lesions follow a defined distribution and do not spread throughout the body. Although the external appearance is striking, specialists emphasize that the associated pain can be the most intense and persistent symptom.
Antiviral medications, when administered within the first 72 hours of symptom onset, can shorten the duration of the illness and reduce the risk of complications. However, when diagnosis is delayed, one of the most feared long-term effects can appear: postherpetic neuralgia, a persistent pain that can last for months or even years after the rash disappears.

Those who suffer from it describe a constant burning or stabbing sensation that interferes with sleep, rest, and daily activities. For this reason, doctors stress the importance of not minimizing initial symptoms and seeking medical advice immediately if any suspicion arises.
