Postherpetic Neuralgia -

Postherpetic neuralgia (also termed PHN) is a condition of recurring or persistent pain in an area of the body that has undergone an outbreak of herpes zoster virus (HZ), also known as the varicella zoster virus, commonly termed shingles. It usually begins after shingles lesions (blisters) begin to crust over and heal but may occur in some patients who do not produce lesions.

Symptoms -

Pain that lasts 3 months or longer after the shingles rash has healed. The associated pain has been described as burning, sharp and jabbing, or deep and aching. Sensitivity to light touch. People with the condition often can't bear even the touch of clothing on the affected skin (allodynia). Itching and numbness. Less commonly, postherpetic neuralgia can produce an itchy feeling or numbness.
