Herpes neuralgia usually refers to the nerve pain caused by herpes zoster, and the treatment includes general treatment and medication. 1. General treatment: patients need to keep the rash clean and dry to reduce the risk of the rash becoming infected with bacteria. Loose clothing can be worn to reduce the risk of friction and blister rupture. 2. Medication: For patients with shingles, they should take oral antiviral drugs, such as acyclovir, vasiclovir and famciclovir, which can shorten the course of the disease and reduce the severity. If the patient develops neuralgia, oral medications such as gabapentin and pregabalin can be taken to treat neuropathic pain. For nerve pain caused by herpes zoster, it can also be combined with physical therapy such as red and blue light irradiation, and it is recommended that patients seek medical examination and cooperate with doctors.
