[Polarized light irradiation near the stellate ganglion in a patient with Raynaud's sign].

Polarized light irradiation near the stellate ganglion was performed in a 55-year-old female with Raynaud's sign. She was suffering from cold and numb pain in bilateral fingers for 1 year. Stellate ganglion block and low reactive-level laser therapy near the stellate ganglion were not sufficient to relieve this symptom. Polarized light irradiation near the stellate ganglion induced a sting stimulation and warm sensation in her hands. Thermograms revealed a remarkable increase in temperature of her hands. The results imply that polarized light irradiation near the stellate ganglion increases blood flow of forearms and relieves Raynaud's sign.
