The earliest symptoms of shingles, which include headache, fever, and malaise, are nonspecific, and may result in an incorrect diagnosis. These symptoms are commonly followed by sensations of burning pain, itching, hyperesthesia (oversensitivity), or paresthesia (pins and needles: tingling, pricking, or numbness).
It 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 an itch, in one particular location on only one side of the body. After several days, a shingles rash may appear.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 this pain and its associated rash is a band, called a dermatome, spanning one side of the trunk around the waistline.ometimes, particularly in older people, shingles pain persists long after the rash has healed. This is known as postherpetic neuralgia. Postherpetic neuralgia can be mild or severe -- the most severe cases can lead to insomnia, weight loss, depression, and disability.
