It's been a awful 3 weeks for me a constant feeling in chest/ under ribs like a pressure no pain. Tight feeling along with that I just feel like not air is going on me or too little is. I breathe with my mouth closed and it feels like proper hot air in my mouth. Back of the throat I can actually feel the air go down sometimes. Dr had listened to my lungs so many times and said they are really clear. He doesn't think it's got anything tondo with my heart or lungs etc. As I hardly experience chest pains either. I've noticed wen I'm completely busy I don't notice it as soon as I'm in my own comfort etc bang. Gets to the point I have to have my hand on belly to see if it's going up n down help?
