“I have had the Gunlight fo several days only. I have been suffering from heel pain and moving through my acupuncturist's day has been getting difficult. I Gunlight my heel at night in several different directions and in the morning (not immediately after) the heel is 80% reduced in pain. I will continue this treatment on myself. I have also used on SI16 for insomia patients (bilateral for three minutes each side) and am waiting for response from patients. Thanks for this instument”
