Seasonal changes and RA changes

It seems that after 25 years with this illness the longer I have it the more fall and winters seasonal changes drastically affect me and my illness. Two months ago my blood work was actually nearing normal for the first time in years, I felt really great for about 3 weeks in August and was very active outside puttering around doing yard stuff and projects with very little down time. Then, September came and here in WA fall seemed to come a little earlier than normal and just like in Cinderella *POOF* I turned into a pumpkin. I spend most of my time in front of my wood stove now and will all the way into spring if it's anything like last year.
Does anyone else experience this? I always thought the weather changing stuff was pure hogwash because in spite of severe RA all these years it never really seemed to fit the pattern I heard people talk about at least in my case. about 5 years ago I began noticing that I would have sharp upticks in pain the days that the weather was turbulent and now I swear I can predict it coming before the national weather forecast.
I wasn't prepared for the season changes having that effect though. It really threw me and last year it was much like this one has been. It's very profound the effect it has. To the point that I can't take part in things like Church in the mornings because I only get a few hours each day that I am not too stiff or in too much pain or have actually gotten any sleep the night before. Maybe I'm just getting older and because I am disabled and slowed down a lot I notice these things now where I didn't when I was better able to cope with it in my youth. I really don't know.
It's another one of the mysteries of this illness that just doesn't make much rational sense I guess. Maybe it's just me that's making less rational sense the older I get.

Yes- November was my onset and I flare every November

I am seriously considering later this year heading down to AZ and staying in my camper for the winter months starting in October. I began having flares in Nov and since then they have increasingly gotten worse, in part because I was sick with a major sinus infection that did not respond to treatment and had to stop taking my meds for a prolonged time while treating it. These sinus infections seem to happen year after year as well. December was very hard and by the end of the month I was using my walker and spending almost my entire days in my EZ chair with knees and feet swollen up like balloons. I have hardly been able to move I am so wracked by pain now also in my shoulders, elbows and wrists again.

I know now that I am back on my meds that this will eventually subside and I will be able to get on with things but last year it was the same and my wife actually suggested it as she had been researching RV life on Youtube channels. She works still and I also have two children at home although they are both in their later teens now and forging toward lives of their own. So it would mean going it on my own for the winters at least until she is ready to retire. She works for a school district so she could come to visit at Christmas break at least.

Has anyone tried migrating to a more stable climate for the winter months? If so I would be interested to hear your experience and insights. I am fully disabled now so I dont have much of a disposable income but I do own a nice camping trailer and could pull it down to stay in areas that allow extended stays for reasonable prices. There are quite a few people who do this sort of thing year round now it seems. I think I could manage it if I took my time and planned things out well in advance.

Great pointers, I don't bother with the vaccines because I am not convinced of their effectiveness so I pass on them. I did take them for years but they did not seem to make any difference for me. I do use Volatren especially at night when it is very bad and I can not get comfortable it does help to lessen the pain at least for a short time. I am a big believer in netti pots, in fact I have one that pumps water through your sinuses and it took some getting used to but I wouldn't trade it for anything now.
I think part of my problem with sinuses is that I had sinus surgery some years back and while it helped to alleviate my breathing problems at night it also opened my sinuses up much more and now I am greatly affected by pollens and allergens where as in the past I was not.
I won't be leaving my family, after considering it I would be miserable and I would worry far too much about them for it to be beneficial to anyone.
