Postherpetic neuralgia (PHN) is defined as pain that persists 1 to 3 months following the rash of herpes zoster (HZ). PHN affects about 50% of patients over 60 years of age and 15% of all HZ patients.

Being vaccinated against shingles is the best way to prevent postherpetic neuralgia (PHN), lingering pain from the shingles virus. Here's what you should know about the causes, symptoms, and treatments for this painful chronic condition.
Postherpetic neuralgia. Overview. Postherpetic neuralgia (post-hur-PET-ik noo-RAL-juh) is the most common complication of shingles. The condition affects nerve fibers and skin, causing burning pain that lasts long after the rash and blisters of shingles disappear.
* Postherpetic neuralgiais defined as pain that persists or relapses within 30- 120 days at the site of acute herpes zoster after rash healing. Postherpetic neuralgia Postherpetic neuralgiaor chronic pain is the most common complication of shingles, which can last for months, even years.
The chickenpox (herpes zoster) virus causes shingles. The risk of postherpetic neuralgia increases with age, primarily affecting people older than 60.
How is postherpetic neuralgia diagnosed (PHN)? PHN usually is diagnosed when a patient’s pain lasts more than 30 days after an attack of shingles or for more than 90 days after rash onset.
The pain of PHN, which occurs in the same area as the pain and rash of shingles, results from damage to nerve fibers during the shingles infection. Shingles is caused by a recurrence of the varicella-zoster virus, the same virus that causes chickenpox.
In PHN, pain is intense and may be described as burning, stabbing, or gnawing. Affected areas of the body may be hypersensitive or may have decreased sensation. Areas formerly affected by shingles may show evidence of skin scarring.
PHN is treated with medications including: In some cases, there is a tendency for PHN to improve over time without treatment, but that improvement usually levels off after 1 year from the start of symptoms.
This condition is known as PHN when the pain continues for longer than 4 months after the onset of the rash. PHN occurs most often in older adults and in patients whose immune systems have been compromised. Cleveland Clinic is a non-profit academic medical center.

Postherpetic neuralgia (PHN) is a painful, long-lasting condition. It is more likely to develop in older patients after an attack of shingles (varicella-zoster virus). Even after the severe rash of shingles lessens, pain can continue in shingles-affected areas.
It is very unusual for shingles to develop in the facial nerve. When this happens, the pain-sensing trigeminal nerve, and the acoustic nerve, which registers sensations of hearing and balance in the inner ear, can become affected.
Allodynia is a spasm of stabbing pain triggered by some other sensation that is not in itself painful. A simple light, moving touch across the skin such as friction from clothing, or a light breeze can trigger the pain.
postherpetic neuralgia (PHN), causalgia and hyperesthesia in the dermatome served by a spinal nerve infected by herpes zoster, persisting after resolution of the skin eruption; typically occurs in middle-aged and old people; may continue for weeks, months, or years.

Fothergill's neuralgia tic douloureux (trigeminal neuralgia). geniculate neuralgia Ramsay Hunt syndrome. glossopharyngeal neuralgia that affecting the petrosal and jugular ganglion of the glossopharyngeal nerve, marked by severe paroxysmal pain originating on the side of the throat and extending to the ear.
The neuroma is produced by chronic compression of the nerve between the metatarsal heads. Called also Morton's foot or toe. The pain of Morton's neuralgia is frequently made worse with prolonged standing or walking.

Two common types of neuralgia are that of the trigeminal nerve (see tic douloureux) and that of the sciatic nerve (see sciatica ). adj., adj neural´gic. neuralgia facia´lis ve´ra Ramsay Hunt syndrome.
neuralgia. pain in a nerve or along the course of one or more nerves, usually consisting of a sharp, spasmlike pain that may recur at intervals. It is caused by inflammation of or injury to a nerve or group of nerves.
Morton's neuralgia tenderness or pain in the metatarsal area of the foot and in the third and fourth toes caused by pressure on a neuroma of the branch of the medial plantar nerve supplying these toes. The neuroma is produced by chronic compression of the nerve between the metatarsal heads. Called also Morton's foot or toe.
The following over-the-counter medications may ease the pain of postherpetic neuralgia: 1 Capsaicin. Capsaicin cream, made from the seeds of hot chili peppers, might relieve pain from postherpetic neuralgia. Capsaicin (Capzasin-P, Zostrix, others) can cause a burning sensation and irritate your skin, but these side effects usually disappear over time.#N#Because capsaicin cream can irritate your skin, avoid getting it on unaffected parts of your body. Follow instructions, including wearing gloves for application and washing your hands thoroughly after applying. 2 Topical analgesics and anesthetics. Aspirin crushed and mixed into an absorbing cream or nonprescription-strength lidocaine cream might reduce skin hypersensitivity.
The process takes at least two hours because you need to be monitored after the high-concentration patch is applied, but a single application decreases pain for some people for up to three months. If it works, the application can be repeated every three months.
