I know I’m a little late to the discussion, but I just found this when I was researching. I live in COLORADO, very dry here I have gone into remission with the PMR and life was moving pretty good- then bam there were days that I would wake up and it felt like the very first morning. It hit me a little over a year ago, where I couldn’t even move to get out of bed & I started to notice a pattern. About one to two days before a snow event, which could be 1 inch to 28 inches predicted as the barometric pressure changed so did the pain in my muscles. I’m just a human barometer now. Don’t even have to Doubt the weather persons forecast, I just go how I feel and that means it’s a SNOW event.
