Hello
I know this was 18 months ago but have just come across this post. Hope you are recovered now. Just wondered if you still have the 'jittery' feeling in your upper chest as I have this feeling come and go (have tremors too) When it happens I start to feel agitated although I'm not, it's like a chemical reaction and can last days into weeks. Specialists are at a loss and just say it's anxiety but it's not. I'm due to see an Endocrinologist next month as getting desperate. Any reply would be greatly appreciated.
