The symptoms of shingles include:
Pain or a bruised feeling -- usually on one side of your face or body -- often along with a fever, chills, headache, or upset stomach
Tingling, itching, or prickling skin, followed several days later by a group of fluid-filled blisters on a red, inflamed base of skin
Deep burning, searing, aching, or stabbing pain, which may occur once in a while or last a long time
The affected area becomes secondarily infected with bacteria (indicated by spreading redness, swelling, a high fever, and pus); antibiotics can help halt the spread of bacterial infection but not the shingles itself.
Your rash lasts longer than 10 days without improvement; get treatment to avoid potential nerve damage.
The pain becomes too great to bear; your doctor may prescribe stronger painkillers or a nerve block.
