To Whom this may Concern, 11/11/2022 Well I am a new client . I am still trying to find the right spot for my Nerivio . I have a concussion which I received about 5 wks. I have been using my Nerivio . So I don't know if that holds any weight on how the Nerivio would work and how any differently ? Did you do any clinical testing in this area ? It's just that I'm having to run it twice every time. Thank you in advance for any information you can send me so I can check with my Dr. Maybe then we can find the best place to place it.
