I love my device! I’ve failed just about every medication for migraines. It’s not just a headache, in fact your head may not hurt during migraines. It is an all over body autonomic nervous system event. Through this little neuromodulator, I usually get relief from nausea and all over body pain. Or a headache. Sometimes I take a triptan with it. But this is a game changer. It works! I can’t believe the world of migraines has improved so much since 2009 when migraines took my career away. Very little help offered at that time. The experts said weather was not a cause. Now the researchers agree weather affects migraine by a rising barometric pressure. Every single time it gets me. My Nerivio keeps me going instead of 3-4 days of vestibular system vertigo. The Gear Up sessions are just right as I start treatment. Thank you Nerivio for this miracle. The sooner I use it with first signs of migraine, the more effective it is before my brain is toast.
