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).
Most cases of shingles last 3 to 5 weeks. Shingles follows a pattern: 1  The first sign is often burning or tingling pain; sometimes, it includes numbness or itching on one side of the body. 2  Somewhere between 1 and 5 days after the tingling or burning feeling on the skin, a red rash will appear. 3  A few days later, the rash will turn into fluid-filled blisters.
