I had these for maybe the first 4-6 weeks or so of transition. I think my Testosterone wasn't low enough and the estrogen wasn't high enough. It could just be your body adjusting to things, or you might want to get blood work done just to see where your T and E levels are.
I went through some menopausal symptoms including anxiety, crawling skin, migraine (my first), sweating, shaking, muscle spasms and other stuff. It all went away with time in my case. I hope you figure it out, it did suck when it was happening to me š
