How to get relief from post herpes zoster? please adivse.?

My mother is suffering from herpes zoster since last 14 months.The effected area is left eye and forehead. There is no wound but there is still pain, burning and elergy.

The condition your mother has is called Post herpetic Neuralgia.
Postherpetic neuralgia results when nerve fibers are damaged during an outbreak of shingles. Damaged fibers aren't able to send messages from your skin to your brain as they normally do. Instead, the messages become confused and exaggerated, causing chronic, often excruciating pain that may persist for months 鈥?or even years 鈥?in the area where shingles first occurred.

This complication of shingles occurs much more frequently in older adults. Less than 10 percent of people younger than 60 develop postherpetic neuralgia after a bout of shingles, while about 40 percent of people older than 60 do.

If you do develop postherpetic neuralgia, see your doctor right away. Finding an effective treatment to relieve the pain can sometimes be frustrating. You may have to work with your doctor and sometimes other specialists to try a variety of treatments before you find something that helps.

Herpes zoster is caused by a virus in nerve endings (on the skin) that usually one of the branches of the trigeminal nerve (Cranial Nerve V). My grandfather had shingles (another name for herpes zoster) a few years ago, and the best treatment was symptomatic until the infection resolved itself (remember it is a virus and so, antibiotics won't help). I suggest a cool towel over the affected area when symptomatic (or if always painful, when moreso). Additionally, I would have your mom's doctor see if there's an underlying immunodeficiency, often caused by some cancers.
