I believe a lot of it has to do with the covid booster in particular. I think if you had certain underlying conditions this shot brought them out. But we’ll never really know the real truth. This is all my opinion. Many will disagree but many will agree.

MG effects our nervous system right?
Its a break down of your muscles not receiving that message from your nervous system telling it what to do.
2017 and research on MG was literally dumped onto the internet. Not many doctors were caught up at the time.
I found out in 2022 because my MG came out of remission and I was in near crisis.
It was like going back to college. And I had to be expidited thru my classes.
MG symptoms look like a bunch of other auto immune dieases and so it may be a lot of mis dx's.
There are only a few doctors around where I live that really understand Mg and only one who is an expert. He was mine up until earlier this year. (A story for another time)
He sees up to 40 patients a day.
All that being said, doesn't mean there is an uptic in diagnosed patients as it can mean those of us that do have it are having an uptic in flare ups and unfortunately crisis because of the state of our union is very stressful . And life just keeps lifing

live well

That's an interesting observation and you could be spot on.

I also wanted to add to my first response. My whole life has been pretty much full of stress, trauma, abuse. I never got time to recoup then something else would happen.
My MG hit with a crises in my mid 70s
I think my body was broken down.

It's uncanny
