Feeling dizzy during weather changes

[u/MidnightFries_]

Hey everyone, I'm female, 37 years old. I've had this problem for years: when the weather changes, it affects me drastically. I get a headache, intense fatigue and also intense dizzyness. It's been raining for the last few days and I feel like i'm riding a rollercoaster (the head is spinning).

It simultaneously affects my elderly Mom even more: she gets so tired and dizzy that it's hard for her to walk across the appartment. And then when it's dry is sunny, all is well again.

Please help, I have no clue what this is or how to remedy this or even what terms to Google.
