Looking for Help with Cyclic Migraines in General Board Posted July 25, 2018 Thanks everyone for weighing in. I'm going to give the D3 regime a try. As for oxygen, I don't think that will be easy for me to obtain through my doctor or approved via insurance as I don't have CH, any ideas on how to get it otherwise? I will also talk to my neurologist more seriously about botox, I know I've tried enough preventatives that I can qualify, and have frequent enough migraines. I asked him at my last appointment about the new drug Aimovig, he said that he will likely be slow to start prescribing that as drugs that have targeted CGRP in the past have had problems with toxicity, and it's currently $8,000/year which is prohibitively expensive for most (including me).
