Herpes Zoster is a viral disease that affects the skin and the ganglia in the spinal nerves. The disease causes damage to the myelin nerve fiber, which is characterized by the emergence of intensely painful macro papules and vesicles borne by the skin dermatome concerned. Laser photobiomodulation is now a treatment option for this disease. Low-power laser therapy activates the lymphatic and blood microcirculation, increases the level of endorphins with painkiller and anti-inflammatory effects and accelerates the regeneration of nerve and skin tissues. It is contraindicated in patients with pacemakers, epileptic patients and pregnant women.
