I have been feeling that that since august 2019, not even a year a bit uncomfortable but it’s manageable. Doctors tell me my EKG is normal. My heart rate is normal, oxygen is normal. It’s that one good satisfying breath I usually have trouble taking. I don’t have shortness of breath cause I feel fine it’s that one deep breath. Even with my yawning. I do like half a yawn and it stops.. a nurse I’d have this past week is so positive that my hormones are imbalanced. Blood work they done was normal. So basically I’m a healthy human being.
