According to the shape and symptoms you described, this is what people often call herpes zoster. What causes herpes zoster is still inconclusive. Many researchers believe that it is related to today's fungal infections, decreased immunity and allergic reactions to certain metal elements. It is suggested that you use some antifungal drugs externally to avoid skin infection caused by scratching blisters, ensure that the affected area is ventilated and dry, and apply some hormone ointment properly, which will quickly relieve the symptoms. If it is painless, it may be more conducive to the recovery of the superficial skin of the affected area, and then take measures to improve the body's immunity and finally eradicate the patient.
