Websites such as ShinglesInfo.com and Zostavax.com display images of shingles on various parts of the body, including the legs. The most common place for shingles to break out is the torso, but the rash can appear at any point on the body, notes Merck, the manufacturer of shingles vaccine Zostavax.
The cause for shingles is the varicella zoster virus. Outbreaks generally show up as a strip or band of blisters on one side of the body or face. People who are most likely to develop shingles are older or suffer from immune system disorders resulting from injury, stress, illness or a mediation regimen, as stated by WebMD.
It is not possible to get shingles from someone who has the virus, even during the middle of an active outbreak. However, a person with an active rash may be able to spread the virus to someone who has not had the chickenpox or the chickenpox vaccine, as the fluid from the rash may transmit the virus, according to WebMD.
When the virus causing chickenpox begins acting up again within the body, shingles occurs. One of the first symptoms is often a headache or sensitivity to light. Others start with flulike symptoms. After a time, pain, tingling and/or itching may set in at a particular spot on the body, followed by a rash, strip or band in that area several days later. The rash develops into blisters, which add fluid and then form a crust. The blisters should heal within a month but can lead to scarring. In some cases, the rash breaks out on the face, or the shingles alters vision or even mental processes, reports WebMD.
