Hi I am having hollowness in my chest, that wakes me during the night, and early in the morning, it's as if I need to eat to fill up the hollowness, but at the same time I get the urge to vomit, but since its either late at night or early in the morning and my stomach is empty I can't, this feeling is very uncomfortable. It is not a lung collapse as I have had 6 lung collapses, and 2 surgeries to correct this problem which is spontaneous. I am female, 5' 2" tall and I never smoked.....help please
