Shingles (herpes zoster) results from a reactivation of the virus that also causes chickenpox. With shingles, the first thing you may notice is a tingling sensation or pain on one side of your body or face. Painful skinblisters then erupt on only one side of your face or body along the distribution of nerves on the skin. Typically, this occurs along your chest, abdomen, back, or face, but it may also affect your neck, limbs, or lower back. The area can be very painful, itchy, and tender. After one to two weeks, the blisters heal and form scabs, although the pain often continues.
The deep pain that follows after the infection has run its course is known as postherpetic neuralgia. It can continue for months or even years, especially in older people. The incidence of shingles and of postherpetic neuralgia rises with increasing age. More than 50% of cases occur in people over 60. Shingles usually occurs only once, although it has been known to recur in some people.
There are a number of ways to treat postherpetic neuralgia.
Medications for Postherpetic Neuralgia
Some of the medications used to treat the symptoms of postherpetic neuralgia are:
Anticonvulsants. These drugs were developed to control seizures. But they can also help reduce the pain of postherpetic neuralgia. Examples are:
Also, Horizant (gabapentin enacarbil) and Gralise (gabapentin) are...
Shingles arises from varicella-zoster, the same virus that causes chickenpox. Following a bout of chickenpox, the virus lies dormant in the spinal nerve cells. But it can be reactivated years later when the immune system is suppressed by:
