When I open my mouth, and I twist my chest it feels like air is coming in and out a little bit making a light “ahhhh” sound, I’ve never heard it before and it’s not painful. I’ve had issues with my lungs before and I don’t know what’s causing this noise, after I twist my chest it feels weird to breath for a little bit but then everything feels normal after about 1 min. No pain at all, am 15 5”9 ~160
