I am considering relocating to reduce the number and intensity of my migraines. I live in an area that is very affected by strong Chinook winds. The migraines are more frequent and intense when the winds are blowing. However, I am concerned that some other trigger will develop and the relocation will just be an expensive disruption to my life.

I have suffered from migraines all my life with the exception of the 10 years when I lived and worked in Jersey in the Channel Islands. Despite my job being a stressful one in a Merchant Bank I can honestly say my migraines decreased dramatically. Every time I went home to NI my migraines increased again, I always put it down to the sea air.

I would like to hear about people relocating as a preventative. Did it work?

I've run the gambit of treatments, but mine seem very weather related that's why I've considered relocating.

No, but a few people have suggested it to me because everytime I leave Texas and go to another area I feel better. I'm not sure if it's the reduced stress or the combinations of allergies here. There was a journalist that wrote an article about this. She got very ill with migraines and other issues when she moved here. A combo of pollen, ragweed and our air pollution was the cause. She did relocate.
If it were for a treatment I would just travel back and forth if possible. Or try to find availability close to home. Most doctors only want to follow up with you every 2-3 months anyway. Some will even do phone consultations. I did this when I was going to the Diamond Headache Clinic in Chicago while living in Texas.
The only other reason I've heard of people relocating is for medical marijuana since it's only legal in a few states.
Mind me asking what sort of treatment your going for?
