Folklore suggests the cold makes pain worse - but there is actually little research into the weather's effects. And this University of Manchester study of 2,500 people, which collected data via smartphones, found symptoms were actually worse on warmer, damper days. Researchers hope the findings will steer future research into why that is.

I took part in this study, and I definitely find the weather influences my pain. I haven't read the full report yet, but I'm not surprised they found some level of influence at least.
Definitely a weather effect . Low pressure is biggest issue - as this is a harbinger of higher humidity it makes sense.
