Before NERIVIO I HAD ONLY IMATREX AND ADVIL AND ZOFRAN. Now I can use my meds plus NERIVIO and 75% of the time knock out an attack. If a second treatment is needed - No Biggie, I just switch arms wait 30 minutes and do another treatment for 45 minutes. I have success 85% of the time. I’m 14 years old and my first migraine was at age 5. Although I’m young to most people, my migraine history is already a long and painful history. Last September, October and part of November of 2020 I had a severe migraine for 67 days straight. Then Dr. Irwin at UCSF told me about NERIVIO and within a week I had the device and did 2 treatments and stopped the migraine. I need the NERIVIO treatments about 3-4 times a week. I am so grateful to have a medical device to turn to for help when I’m at my lowest in pain from migraine. Thank you Robbie Virden
