Hi. Yes, absolutely Barometric changes affect my Fibro, esp. if the weather changes in a short period of time, i.e - a couple of hours. I live in Vancouver, which has a lot of rain. I find that humidity & if the air is damp, that also bothers me. But-- I find if we have snow for a while, it does not, usually bother my Fibro-- because the snow is dryer than the rain. I also find that when daytime is starting to go into evening, i.e. -around 4 pm, that is when I start to ache as well, I feel it starting across my shoulders, then I am aching, then I look at the clock, & yes it is 4pm.. My body LOVES the dry desert air in Nevada/ Arizona. As soon as I get off the plane, I can feel my whole body going YES!.
