Oddly enough, this morning I was writing a Facebook post about the level of pain I was and still am experiencing. I have known since my PsA became that it usually coincided with changes in weather fronts and storms. I had heard or read something a while back that it was related to fluctuations in barometric pressure that accompany the weather and such. I wanted to check it out to be sure to not pass on something I dreamed up 😀 I will post the pertinent section below. I hope it helps!
"The Arthritis Foundation says:
"Changes in barometric pressure can cause expansion and contraction of tendons, muscles, bones and scar tissues, resulting in pain in the tissues that are affected by arthritis. Low temperatures may also increase the thickness of joint fluids, making them stiffer and perhaps more sensitive to pain during movement." - Arthritis.org
Studies on that site and out of Harvard seem to focus on the wording of people claiming its the rain, overall humidity in the air, or temperature. This they dismiss, not acknowledging that the barometric fluctuations that accompany those things does affect those people, they just didnt use the correct terminology.
It seems to me that barometric pressure would also play havoc with synovial fluid, if i have any of that left. Couldnt find any studies on that or even theories."
