Last night I woke up throughout the night with very uncomfortable chest sensation. It's like a pain/pressure/ fullness in the chest. It's happened that bad several times and I've gone to the er like 4 times throughout the year, to make sure it wasn't a heart issue. I always get what you describe as a feeling of trouble breathing as well. I bought a pulsometer because of this to make sure I'm not actually having trouble breathing, since I've had those symptoms. I think it's the pressure from the gas or acid causing all of these feelings but idk. Every time I've gone to the ER they say my chest and lungs are fume and they've done numerous tests throughout the years.

I know when it happens also I have that constant need to burb and I feel like it's all stuck in my upper chest. Sometimes I get a sore throat too from the acid, I assume.
