The Tx360®allows your doctor to administer a nerve block to the SPG painlessly and with extreme accuracy. In less than a minute. The numbing agent administered works on the ganglion area to prevent pain signals from reaching the brain. Resulting in immediate pain relief for headache and facial pain conditions. The procedure is performed as an outpatient service in your doctors office. SPG blocks have been effective for both short- and long-term treatment of headaches and migraines.
