Shingles (herpes zoster) is an outbreak of rash or blisters on the skin that is caused by the same virus that causes chickenpox — the varicella-zoster virus. The first sign of shingles is often burning or tingling pain, or sometimes numbness or itch, in one particular location on only 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. 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 in the original battle with the varicella-zoster virus, some of the virus particles 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.
For most healthy people, the lesions heal, the pain subsides within 3 to 5 weeks, and the blisters leave no scars. However, shingles is a serious threat in immunosuppressed individuals — for example, those with HIV infection or who are receiving cancer treatments that can weaken their immune systems. People who receive organ transplants are also vulnerable to shingles because they are given drugs that suppress the immune system.
A person with a shingles rash can pass the virus to someone, usually a child, who has never had chickenpox, but the child will develop chickenpox, not shingles. A person with chickenpox cannot communicate shingles to someone else. Shingles comes from the virus hiding inside the person's body, not from an outside source.
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. Antiviral drugs may also help stave off the painful after-effects of shingles known as postherpetic neuralgia. Other treatments for postherpetic neuralgia include steroids, antidepressants, anticonvulsants, and topical agents.
The shingles vaccine is only a preventive therapy and is not a treatment for those who already have shingles or postherpetic neuralgia.

Chickenpox is a viral illness that generally starts with a fever. There are multiple small, red bumps on the skin that become thin-walled blisters filled with water. These become cloudy blisters or open sores and finally dry up with brown crusts (all within 24 hours). There are repeated crops of these sores for 4 to 5 days. The rash is on all body surfaces, but usually starts on the head and back. Some sores may be in the mouth, eyelids or genital area. There may be an exposure to a case of chickenpox 2-3 weeks earlier.
Chickenpox is caused by a highly contagious virus known as varicella-zoster virus. The varicella virus belongs to the Herpes group of viruses.
The fever is usually the highest on the third or fourth day. Children start feeling better and stop having fever once they stop getting new crops.
Siblings will come down with chickenpox in 7 to 21 days. The second case in a family generally has many more chickenpox sores than the first case.

I got diagnosed with herpes virus (type 2) about 5 years ago, while I was still attending college and had a mindless one-night stand. I understand a lot of girls will say this, but I swear I had certainly not done that sort of thing before. I just made a mistake that one time and suddenly it seemed like I was going to have to live with the implications for my entire life. The worst part was feeling I could never date men again. In the end, who wants to go out with a girl that has sores around her private parts? But since a friend shared this video https://tr.im/oHUob everything changed.
Not only was I able to eradicate all remnants of the hsv from my system in less than 21 days, but I was also able to begin dating again. I even met the guy of my dreams and I'm so lucky to write that just a week ago, in front of everyone in a crowded restaurant, he got down on one knee and proposed to me!! This system gave me back the chance to be happy and experience true love. Now I want to help you too by sharing this with the World.
