Shingles can appear on various parts of the body, such as the head, face, neck, chest, abdomen, and even the extremities. Because herpes is mainly distributed along the nerves, it mainly affects the trigeminal nerve. On the head and face, it mainly affects the facial nerve, and on the neck, the cervical nerve is mainly injured. If it occurs in the chest, it mainly causes damage to the intercostal nerves. Occurring in the lumbosacral region, it often causes sciatic neuropathy. In summary, shingles can occur on all parts of the body, but the herpes usually does not extend beyond the midline and usually occurs on only one side of the body. If it is bilateral, it is usually not considered shingles.
