For those few patients who develop PHN, the length of time that PHN lasts is variable; the majority of PHN patients have discomfort lasting one to two months. About one-third of PHN patients have symptoms that last about three months, and about one-fifth last a year or longer.
Keeping this in consideration, is there any treatment for postherpetic neuralgia?
Postherpetic neuralgia affects nerve fibers and skin, causing burning pain that lasts long after the rash and blisters of shingles disappear. The risk of postherpetic neuralgia increases with age, primarily affecting people older than 60. There's no cure, but treatments can ease symptoms.
What are the symptoms of postherpetic neuralgia?
Common signs and symptoms of postherpetic neuralgia include:
- severe pain that continues for more than one to three months in the same place that the shingles occurred, even after the rash goes away.
- burning sensation on the skin, even from the slightest pressure.
- sensitivity to touch or temperature changes.
Can shingles cause permanent nerve damage?
Doctors call it postherpetic neuralgia or PHN. It's caused by nerve damage left behind by a case of shingles. Shingles itself comes from reactivation of a chickenpox virus, varicella zoster. The virus travels down nerve fibers to cause a painful skin rash.
