I have lived with migraine for more than half my life - episodic/chronic and now now intractable for the last 5 years. I have been at my wit's end more than once thinking that there was nothing that would help me cope with the unrelenting pain on the worst days. I learned about your device and told my neurologist who had didn't hesitate to submit a prescription. I knew it wasn't intended to treat migraineurs like me, but I was desperate. I was amazed that something so simple could make such a big difference. If I can get it on my arm in time, it will stop the attack from getting unbearable, or even kick it to the curb if I am lucky. I do wish there was a way to get just the device itself with refills and not the pouch and armbands. I feel like it's such a waste to throw them into the trash (although, I have found other uses for the spare pouches). I also hope that Medicare (and the corresponding prescription insurance that goes along with it) will eventually cover the cost of the device; $299 for four devices at a time is a savings but it is still a lot of money out of pocket.
