The herpes zoster virus is responsible for the shingles rash, which is accompanied by other bothersome signs and symptoms. While the blisters and rash are short-lived, the pain caused by shingles may linger for years. Early identification and treatment of the virus can help reduce the duration of symptoms, according to the American Academy of Dermatology (AAD).
Fever/Headache
Before the shingles rash results, a fever or headache may develop. These symptoms may be hard to identify without the accompanying skin irritations.
Burning, Tingling & Pain
Before the shingles rash is visible on the body, burning, tingling, itching and pain may be apparent. In addition, the skin may become increasingly sensitive. These symptoms are generally felt on one side of the body and are present for several days before a rash appears on the same area. Pain accompanying the virus can be so severe that prescription pain medications are prescribed, including corticosteroids to reduce swelling and ease discomfort. According to the AAD, nerve blocks can help control pain, as well as anti-depressants, anti-seizure medications and anti-neuralgia drugs.
Red Rash
The shingles rash typically appears on the trunk and buttocks, though it may arise anywhere on the body, including the face, arms and legs. According to the National Institute of Neurological Disorders and Stroke, the most common location is a band, known as a dermatone, that spans one side of the trunk around the waistline.
Blisters
Following the painful rash, a group of blisters may form on the skin, signaling the shingles virus. These blisters may be present for several weeks, appearing clear at first, and then becoming yellow and bloody. Finally, the blisters crust over and disappear. According to the AAD, blisters that appear on the tip of the nose signal eye involvement, which may lead to complications like vision loss or potential blindness. If treatment is sought soon after the blister outbreak, most healthy individuals will find the lesions heal and pain subsides within three to five weeks, leaving no evidence of scarring, according to the National Institute of Neurological Disorders and Stroke.
