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.
This chronic pain not only affects quality of life but also emotional well-being.
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.
