Ok, I am from east coast and never had headache issue until moving to Denver where it has become a nightmare. I can’t pinpoint exactly what it is tho bc apparently I now have it in Florida as well. I can tell you in Denver, the constant barometric pressure changes are my biggest problem, followed by high altitude, intense sun, dry air and extreme temp changes. Florida never bothered me in past, but I had problems on recent trip although not as bad as Denver. I can’t see the commonality there they are completely different. I’m trying to move somewhere that I will no longer have this issue, but I don’t know if I’m missing something about what Denver and Florida have in common?
Portland, Las Vegas I have visited and had immediate relief of all symptoms including red nose. Obviously I’m trying to visit some move options as time permits, but you only get so much vacation from work and it’s still limited time I didn’t get this when I first visited Denver either. Humidity does not seem to be a problem for me. I don’t know, I’m completely confused about what exactly my triggers are bc Portland is supposed to be awful, but I felt great there, just thinking about it so soothing the moisture and darkness. Anyway, if any weather experts on here, throw in your 2cents please!
