You may be at risk for shingles if you:

How Is Shingles Treated?
There is no cure for shingles, but treatments for the condition can help ease the associated pain and discomfort. Treatments also can help the healing of blisters and rash.
Antiviral medications such as Zovirex, Valtrex, and Famvir can ease discomfort and reduce the duration of symptoms. In most cases, it is recommended that antiviral drugs be started within 72 hours of the first sign of shingles.
Pain medications can also offer relief. Tylenol or over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Motrin, Advil) can be effective in relieving mild pain. For more severe cases of pain, prescription NSAIDs or narcotic pain relievers may be necessary. In some cases, steroids can be prescribed to ease the discomfort, inflammation, pain, redness, and itching associated with shingles' rash and blisters.
Is Shingles Contagious?
Yes. People who have never had chickenpox and have not been vaccinated against the disease can develop chickenpox if exposed to the virus. Also, in women who are pregnant, it's possible to infect the unborn child as well. If you have shingles and start antiviral medication, limit contact with others for at least three days.
