why do I get ill before it rains?

An hour or two before it rains especially after a period of good weather regardless of season I get vertigo and brain fog followed by muscle and joint pain .
I dont know whether its atmospheric pressure or increased humidity which would point to M.S. or am I just SAD?
(I have a preliminary diagnosis of M.E.)
Or should a become a weather forecaster?

hi guys, Me here!

I always know when its gonna rain - my knees ache like mad. Occasionally its so bad that I have to have a pain painkiller and wrap my knees with a big blanket. Havent noticed the moods - I will keep an eye open for that.

I went on a night orienteering course one year, one of the points was supposedly by a stream on the map. We couldnt find the stream initially, then I used my knee trick. Once I got to the stream my knees ached, I called for all to stop. We found it underneath the road just there. Its also useful for knowing when to take a rain coat!! Ive always associated it with pressure change, but maybe not!

Reckon I should take up dowsing for a living!!

Interesting...
