You are absolutely
not alone!
I had the hug a couple of weeks ago and it was the worst case of it I've ever had. It was truly painful. And....I could not get a good, deep breath. It took me several tries to finally get that satisfied feeling of a deep breath.
I've had this sx, too, with the hug and no pain involved. Just the constricting feeling of someone squeezing me.
I hate it when they chalk everything up to anxiety.

Who
wouldn't be a little anxious if they couldn't breath well???
I hope you feel better soon.
