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).
When you get a shingles rash, it typically involves a particular âdermatome,â that is, the skin area supplied by the involved nerve usually on one side of the body or face. However, in some cases the shingles rash can be widespread. Before the rash appears, people may have nerve symptoms of pain, itching, burning, or tingling. The rash has blisters that scab over in about a week. Although shingles isnât contagious, the virus can spread to others and can cause chickenpox.
