Yes barometric pressure! I think it also messes with my ears/sinuses.
My mother has very bad osteoarthritis and I got diagnosed this year with having early onset. At least it's not rheumatoid, her mother had that. My father has terrible Ankylosing Spondylitis, started in his 20s and his back and neck are all fused together. Bad family history and my dad was adopted so I know nothing healthwise of his side.
