The distribution of pain: the distribution of herpes zoster pain is generally along the nerve course, unilateral pain, not more than the midline. The general low back pain is mostly bilateral pain, generalized pain, with little relation to the nerve course. 3. Whether there are skin lesions: herpes zoster has skin lesions, manifested as a large erythema based on the attachment of clusters of small blisters, was distributed in a band, does not exceed the midline.
