Shingles are caused by varicella-zoster, the same virus that causes chickenpox. If you've ever had chickenpox (typically during childhood), this virus is quietly. Shingles isn't just a nasty and extremely painful experience. It can also cause strokes and heart attacks, researchers reported Tuesday. The condition is caused by the reactivation of the chicken pox virus within your body.
The first sign of shingles is often burning or tingling pain which can be severeor sometimes numbness or itch,generally on one side of the body. After several days or a week, a rash of fluid-filled blisters, similar to chickenpox, appears in one area on one side of the body. Shingles pain can be mild or intense.Shingles
Some people have mostly itching; some feel pain from the gentlest touch or breeze. The most common location for shingles is a band, called a dermatome, spanning one side of the trunk around the waistline. Anyone who has had chickenpox is at risk for shingles. Scientists think that some of the virus particles from the original exposure to the varicella-zoster virus,leave the skin blisters and move into the nervous system.
When the varicella-zoster virus reactivates, the virus moves back down the long nerve fibers that extend from the sensory cell bodies to the skin. The viruses multiply, the tell-tale rash erupts, and the person now has shingles. View Full Definition Treatment The severity and duration of an attack of shingles can be significantly reduced by immediate treatment with antiviral drugs, which include acyclovir, valcyclovir, or famcyclovir.
Other treatments for postherpetic neuralgia include steroids, antidepressants, anticonvulsants including pregabalin and gabapentin enacarbiland topical agents.
The varicella zoster virus vaccines Shingrix and Zostavax have been approved by the Food and Drug Administration for adults age 50 and older. The immune system keeps the virus in check, but later in life it can be reactivated and cause shingles. It's possible to have shingles more than once, but it's very rare to get it more than twice. This may be the result of: It's not possible to catch shingles from someone with the condition or from someone with chickenpox.
The blisters that form contain live virus.

Read more about the complications of shingles The shingles vaccine It's not always possible to prevent shingles, but a vaccine called Zostavax can reduce your chances of developing the condition. If you still develop shingles after having this vaccine, it may be milder and last for a shorter time than usual. The main symptoms are pain, followed by a rash. Any part of your body can be affected, including your face and eyes, although the chest and abdomen tummy are the most common areas where shingles develops.
Early symptoms In some cases, shingles may cause some early prodromal symptoms that develop a few days before the painful rash first appears. A high temperature is particularly uncommon.
Pain Eventually, most people with shingles experience a localised "band" of pain in the affected area. The pain can be a constant, dull or burning sensation and its intensity can vary from mild to severe. Pain is less common in young healthy people and is rare in children.
Rash The shingles rash usually appears on one side of your body and develops on the area of skin related to the affected nerve. It usually takes two to four weeks for the rash to heal completely. Causes of shingles Shingles is caused by the reactivation of the varicella-zoster virus, which is the virus that causes chickenpox. It can become reactivated at a later stage and cause shingles.

Your immunity to illness and infection can become lowered if there is a problem with your immune system the body's natural defence system. This can happen as a result of: However, it is possible for someone who has never had chickenpox to catch it from someone with shingles, as the shingles blisters contains the live virus.
In the UK, chickenpox is so common during childhood that 9 out of 10 adults have already had it and will not be at risk from someone with shingles.
