Shingles are painful skin rashes with blisters, which in most cases, develop on one particular side of the body.

Theyare caused by varicella-zoster virus,a type of herpes virus, which is the same virus that causes chickenpox. When you are exposed to this virus, it will initially cause chickenpox. Even after you have fully recovered from chickenpox, the virus lives in your nerve roots forever. However, it becomes dormant and may remain in the same state for years. But, it may reactivate at anytime, and when it reactivates, it takes the form of shingles.

Anyone who has had even a mild case of chicken pox can develop shingles at a later stage. However, this does not mean that everyone who has had chickenpox will develop shingles at some point in their life.

You can contract shingles virus by coming in contact with fluid in shingles blisters on an affected person.
