In short — Postherpetic neuralgia is nerve pain that can linger in the area of a shingles rash long after the skin has healed, most often defined as pain lasting 90 days or more. It becomes more common with age, and topical treatments, nerve-pain medication, or, in selected patients, interventional options may ease it, though relief is often partial and varies by patient.
A patient in Orange Park had a band of blistering, painful shingles across the ribcage on one side two months ago. The rash is gone. The skin still burns at the lightest touch of a shirt, and a stabbing pain flares without warning several times a day.
A patient in Mandarin had shingles near the eye last year, treated promptly with antiviral medication. Months later, a dull ache with occasional sharp jolts remains along the forehead, and no one has fully explained why it is still there.
Both patients are describing postherpetic neuralgia — one of the most common complications of shingles, and one that often catches patients off guard because they expected the pain to end when the rash did.
What is postherpetic neuralgia?
Shingles (herpes zoster) happens when the varicella-zoster virus, the same virus that causes chickenpox, reactivates in a nerve years after the original chickenpox infection. It typically produces a painful, blistering rash in the distribution of a single nerve, most often on one side of the trunk, though it can affect the face, including around the eye.
Postherpetic neuralgia is the nerve pain that persists in that same area after the rash has healed, most commonly defined as pain continuing 90 days or more from when the rash began. The virus damages the affected nerve during the acute infection, and that nerve damage — not an ongoing infection — is what generates the lingering pain.
A common point of confusion: doesn't the pain end when the rash does?
A common assumption is that once a shingles rash clears, the illness is over. For most people that is true, but for a meaningful minority, especially older adults, damaged nerve fibers continue sending pain signals well after the skin has returned to normal. This is not a sign that the shingles is still active or contagious — it is a separate, after-the-fact consequence of the nerve injury the virus caused. (An active, blistering shingles rash can spread the virus to someone who has never had chickenpox or the chickenpox vaccine; once the rash has crusted over and healed, as in postherpetic neuralgia, it no longer poses that risk.)
It is also not something a patient did wrong. Postherpetic neuralgia is more strongly tied to age, the severity of the original episode, and how quickly antiviral treatment started than to anything within a patient's control after the rash has already appeared.
Who is more likely to develop it
Risk rises with age, particularly after 60, and increases further with each decade after that. Other factors associated with a higher risk include more severe pain or a more extensive rash during the acute shingles episode, a delay in starting antiviral treatment, shingles affecting the face or eye, and a weakened immune system from illness or medication.
What this means for patients
Pain that continues after a shingles rash has healed is common enough that it has its own name and its own body of treatment evidence — it is not something to simply endure without discussing it with a physician. At the same time, not every patient needs the same treatment, and the right approach depends on how long the pain has lasted, how severe it is, and what has already been tried.
Treatment options, depending on the diagnosis
Care is typically stepped, starting with the options that carry the least risk and moving toward more targeted therapy if pain does not improve enough. Options that may be considered, often in combination, include:
- Topical treatments applied directly over the painful area, such as lidocaine patches or capsaicin cream; a stronger, clinician-applied capsaicin patch is also an option in some cases and is a different product from over-the-counter capsaicin creams
- Oral medications developed for nerve pain, such as gabapentinoids or certain antidepressants, sometimes requiring more than one trial to find the best fit and dose
- Short courses of other pain medication for flares, used selectively and under a physician's guidance
- For selected patients whose pain remains disabling despite these measures, a referral for interventional evaluation, which may include targeted nerve blocks or, in carefully selected refractory cases where evidence remains limited, a case-by-case discussion of peripheral nerve stimulation aimed at the specific nerve territory involved, including its own trial period and risks
None of these options works identically for every patient, and interventional treatment is not the first step for most people with postherpetic neuralgia. The right plan depends on how long symptoms have lasted, their severity, and what has already been tried.
Can it be prevented?
The shingles (Shingrix) vaccine substantially lowers the risk of developing shingles at all and, by extension, the risk of postherpetic neuralgia; it is recommended for most adults age 50 and older, including many who have already had shingles once. For someone who already has an active shingles rash, starting antiviral medication promptly — ideally within 72 hours of the rash appearing — may reduce the severity and duration of the pain that follows, which is one reason new shingles symptoms are worth evaluating quickly rather than waiting to see if they resolve on their own.
When to seek urgent care
Shingles affecting the tip, side, or bridge of the nose can involve the eye and needs prompt evaluation by an eye specialist, since untreated eye involvement can threaten vision. Shingles involving the ear — pain, blisters in or around the ear canal, new facial weakness, hearing changes, or dizziness — can signal Ramsay Hunt syndrome and also needs prompt evaluation, since early treatment gives the best chance of protecting facial nerve function. Fever, confusion, a rapidly spreading rash, new weakness beyond the affected area, or shingles in a patient with a significantly weakened immune system also warrant prompt medical attention rather than a routine follow-up visit.

The bottom line
Nerve pain that continues after a shingles rash has healed is a recognized, common complication with its own name and its own treatment ladder — it is not something patients are expected to simply live with indefinitely. For most people, symptoms gradually ease over time as the nerve continues to heal, and topical treatment or nerve-pain medication may reduce the pain in the meantime, though relief is often partial; for those whose pain does not improve enough, a physician evaluation can determine whether additional options, including interventional care, are a reasonable next step.
A shingles rash that has healed but left behind burning, stabbing, or touch-sensitive pain is worth mentioning at the next appointment, not something to wait out on the assumption that nothing more can be done.
Frequently Asked Questions
What is postherpetic neuralgia?
Postherpetic neuralgia is nerve pain that continues in the area of a shingles (herpes zoster) rash after the rash itself has healed, most often defined as pain persisting 90 days or more from the rash's onset. It happens because the same nerve inflammation that caused the shingles rash can leave lasting nerve damage even after the skin looks normal again.
Who is at higher risk of developing postherpetic neuralgia after shingles?
Risk increases with age, particularly after 60, and is higher in people who had more severe rash or more severe pain during the acute shingles episode, a delay in starting antiviral treatment, or a weakened immune system. Shingles involving the face, especially around the eye, is also associated with a higher risk of lasting nerve pain.
How long does postherpetic neuralgia typically last?
For many patients, postherpetic neuralgia gradually improves over weeks to months as the nerve continues to heal. In some patients, particularly older adults, pain can persist for a year or longer, and a smaller number of patients have pain that continues indefinitely. The course varies by patient and cannot be reliably predicted in advance.
What treatments may help postherpetic neuralgia?
First-line options include topical treatments such as lidocaine patches or capsaicin, and oral medications developed for nerve pain such as gabapentinoids or certain antidepressants. When pain persists despite these measures, interventional options such as targeted nerve blocks or, in selected refractory cases where evidence remains limited, a case-by-case trial of peripheral nerve stimulation may be considered after a physician evaluation.
Can postherpetic neuralgia be prevented?
The shingles (Shingrix) vaccine substantially reduces the risk of developing shingles in the first place and, by extension, the risk of postherpetic neuralgia, and is recommended for most adults 50 and older. For someone who already has shingles, starting antiviral medication promptly, ideally within 72 hours of the rash appearing, may reduce the severity and duration of the pain that follows.
When does shingles or postherpetic neuralgia need urgent medical attention?
Shingles affecting the tip, side, or bridge of the nose can involve the eye and needs prompt ophthalmologic evaluation, since untreated eye involvement can threaten vision. Shingles involving the ear, with pain, blisters, facial weakness, hearing changes, or dizziness, can signal Ramsay Hunt syndrome and also needs prompt evaluation to protect facial nerve function. Fever, confusion, a rash that is spreading widely, new weakness beyond the affected area, or shingles occurring in someone with a significantly weakened immune system also warrant prompt medical attention rather than waiting for a routine appointment.
