Hello, i'm unmarried 25 yrs old female. From past 1.5 months i'm facing issues where suddenly i can't breathe, even taking deep breaths is not helping then i start yawning with no breaths which is followed by burping. This started happening once a week in beginning but now it happens alternative day. The whole thing last for 1-1.5 hr but its very discomforting. Kindly suggest is this some gastric issue or pulmonary issue.
