Hey Linda,
I live in Maryland and can say with certainty that the weather absolutely affects me. Mostly, it amplifies my fibro, RA and CFS symptoms. It's not a particular weather (like getting coler) that is the culprit. For me, it tends to be the change in barometric pressure. That's the killer for me.
In 1996, my wife and I went to vegas in July to take part in a wedding. It was 107 degrees and dry, dry heat. No humidity at all. At that point, I'd had FM for five years and I NEVER felt better than those four days in Vegas. After my return to Maryland, my wife and talked about going back there, even if it was just me, so that I could feel better during a bad spell - sort of an injection of Vegas. Ten years later, my father and I decided to go for it and spent five days at the Mirage Casino. We took a glass plane ride over the Grand Canyon, spent an afternoon at Red Rock, took in a few shows, ate at Emril's restaurant and lost a good bit of money (so much for my system!). I actually ate a Kobe steak and it is everything they say it is.
Here's the problem - I had a major flare in the middle of the meal at Emril's restaurant. The food was excellent but my fibro kicked in and ruined the meal. It hurt me to watch my father se me in such pain. I did my best to mask it, but at that point, there was little I could do.
Another story involves when my daughter was five and my wife and I took her to Disney World as part of a FM conference which I presented. It was a record high for three straight days (anywhere from 97 to 102). I had a major flare before we left. I needed a wheelchair in the airports and a scooter to get around the conference and Disney World. I had been to Orlando before my daughter was born tagging along with my wife as she had been asked to present at a professional conference. That time I felt great.
Upon arriving home from Vegas, I contacted my friend on the Board of the National FM Partnership (I was a board member for more than ten years) and told her about my two Vegas experiences. The bottom line is that there are people with fibro in every state, in every county, in every town. The weather may help but it will not change the fact that you have Fibro and will have to deal with fibrofog, pain, fatigue, sleep issues, cognitive issues, etc.,
My wife and I are now seperated and my only child is a senior in high school. Seven of the nine universities she is applying to are beyond my ablity to get in a car and drive as they are nine+ hours or so away. Once she leaves, other than my doctors and friends, I have no reason to remain here. I do not think I want to go back to the area I grew up (Cherry Hill, NJ in the suburbs of Philadelphia). I'm seriously considering moving somewhere that is remote and I know nobody - ca chance to remake my life. I loved Boulder, CO when I visited in the 1990's when I was being recruited for job. I've considered going south-south but to be honest, I love the four seasons even if it affects how I feel.
I hope I have given yu some information that will help.
