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).
The blisters will gradually grow smaller before disappearing and scabbing over in about seven to 10 days. Other early symptoms include tiredness, aching muscles, headaches, nausea, general feeling of being unwell, and fever. Shingles symptoms commonly last between 2 to 4 weeks.
