What happens, what does it feel like? How do you correct it, and how often does it happen to you personally?

Hello, welcome to the forum!

Here is a link to a thread that addresses your question.

"Stuck"

I actually got my first fill so haven't had any episodes yet... I hear it's nasty~

It's kind of hard to describe, but when it happens, you definitely know. I describe it as a painful pressure in your chest and then everything comes up and relief!!.... well, it only happened once to me so that was my experience.
