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.
