Weather changes BP

We have been socked in with overcast for 3 weeks here in the harbor, and today the sun was bright and blazing for the first time in almost a month. My body went slightly bonkers readjusting, BP dived all morning, and I was having slight spasms at the back of my tongue on and off, and the bowel was a bit off too. The barometric pressure weather changes always seem to raise hell for me. And the tongue thing bothers the daylights out of me, it happens now and then with the weather going from Fogged in to sunny. Go Figure it.

This is an old post, but I wanted to weigh in. Barometric changes, especially going from warm to cold or just before a storm system comes in, wreck havoc with my body also. I get aching eyes, sinus congestion, headache, feel extra fatigued, sometimes whole body aches, depressed.
Interestingly, my neighbor, who has Lupus, feels rotten on the same days that I feel rotten and better on the same days I feel better. Just like clockwork.
This seems to me to suggest an underlying auto-immune mechanism with CFIDS ...
