Hello, for some reason, every time I breathe in, I get this weird gas-like sensation in my chest and it follows up to my throat (like an empty air pocket). I have no idea what this is. I've been waking up with it and it basically occurs all day. Burping doesn't really solve it.vim also very fatigued a lot, have dry eyes and skin, and haven't been exercising like I used to (I'm afraid to because I have heart worries). It's uncomfortable and in freaked out that's it's something severe! I'm a 24 year old male who's had 3 EKGs, 2 chest x-rays, and a stress EKG because I always wake up with tachycardia and struggle with heart palpitations/extrasystoles. Help! I'm afraid to go to sleep!
