Herpes zoster should be treated in dermatology, and patients should visit the dermatology department. Herpes zoster, also known as shingles, is an acute vesicular skin disease caused by the varicella-zoster virus, which is particularly common in the spring and autumn seasons. It mostly affects adults and is even more prevalent among the elderly. Before the rash appears, there may be varying degrees of prodromal symptoms such as fever, fatigue, and loss of appetite. Neuralgia is a characteristic of the disease, and pain can occur before or after the eruption of the rash. The rash follows the distribution of cutaneous nerves, with the most common areas being the intercostal nerves, cervical nerves, trigeminal nerves, and sacral nerves. The rash is usually unilateral and does not typically cross the midline of the body. The duration of herpes zoster is about two to four weeks for recovery, and generally, it does not recur after healing. However, some elderly and frail patients may suffer from chronic pain as a sequelae, so timely medical consultation is important.
