Postherpetic neuralgia requires a visit to a dermatologist or pain management unit and may require a visit to a psychiatrist if necessary. Patients with postherpetic neuralgia may see a dermatologist for oral medication, physical rehabilitation, and other treatments as directed by a physician. Patients with postherpetic neuralgia may also be seen in the pain department for oral medication and minimally invasive interventions under the supervision of a physician. Psychological factors can significantly affect the perception of pain, and patients with severe anxiety and fear need to go to a psychiatric clinic for psychotherapy. Postherpetic neuralgia is the most common complication of herpes zoster, which seriously affects the quality of life of patients, and it is recommended that patients consult dermatologists or pain medicine departments in a timely manner, and if necessary, consult psychiatrists, and choose the medication and treatments under the guidance of doctors.
