I agree with you; you know your own body better than anyone else. The average 'lazy doctors' medical contention that you start by ruling out psychological causes of health issues before you investigate physical health issues annoys the hell out of me. There is a medical term called 'secondary to' referring to something having been caused by another thing. If you have real health problems then you will psychological issues 'secondary to' the health problems. After I collapsed at work I began to experience issues with dysfunction of the upper oesophageal sphincter, as a consequence affecting the function of my epiglottis. This resulted in both aerophagia and aspiration in my own case.
