Look i am not denying doctors can make mistakes. But if this breathing symptom is not worsened by exertion i.e running then it is not true shortness of breath which means yes the feeling is very real but it false as they say pseudodyspnea. in that case, i am not preaching for everyone only in that case where its false, then it is either anxiety or the infamous damage to the espohagus from gerd (very strong link between reflux and anxiety also btw anyways). Guys no one could convince me it was anxiety, but i just want to help those who have tried all the avenues and are left hopeless because i know its very hard to convince any of the people who are still certain this is a physiological reason to this. If anyone is considering the possibility it is anxiety please read my other posts. Anxiety doesnt present in the way you all believe it is not the same as stress or worry, you can be worry free and have awful physical symptoms
