I have heard that changes in barometric pressure can exacerbate symptoms.
Hope you feel better soon.
I think any drastic change in weather can cause a spike. I have a lot of issues with inflammation, which I think is very sensitive to changes in humidity.
Where I am we are having an Indian Summer with daytime highs in the 80's but chilly (40's) at night, and that is causing me a lot of extra joint pain and stiffness. On the plus side, it has been beautiful out with lots of fall colors!
Hope you feel better soon.
