I suuffered with migraines and non-migraine heachaches all the time from the time we moved to Denver when I was 5 until I recently moved to Phoenix at age 53.
Not only do I not have my daily non-migraine headache, but no migraines either even when I do things that would always give me a migraine in Denver. (Not that I try to trigger one.)
I have had just a few non-migraine headaches here in Phoenix, but they were much much less severe and not nearly as often. OTC Tylenol got rid of them.
For people who have tried everything, I suggest taking a vacation to Phoenix or Tucson and see if it works for you too. I noticed the first week here what a huge difference it was.
If thinking of moving here come in summer first to see if you can handle the heat. I am willing to take the heat compared to living with those horrible migraines.
I still use beta blockers daily and always will for prevention.
What a relief it is to not have to constantly be taking prescription pain killers and triptans all the time!
