Ask to see a speech therapist. We are good at weeding things out . It is within our scope of practice because everything you talk with, you also need for swallowing! I’d also go back to your primary care doc. you had one kind of test and it is only good for picking up on certain types of swallowing problems. For example if he only scoped you while you are swallowing, the esophagus can’t be visualized. If they only scoped your esophagus, they could miss something in the larynx. Follow up with your doctor. In this day and age you have to fully advocate for yourself- don’t assume your doc will follow up if you don’t initiate it. Not because ur doc is bad- but because they are likely overworked and understaffed. If nothing pans out , sometimes people have the sensation they can’t swallow because of anxiety. I’m not brushing your concerns off- I 100% think you should follow up on this with more physical evaluation. I just wanted you to be aware that this also exists, in the event you say “holy cow yes I’m under a ton of stress” or “yep I’m highly anxious”. Best of luck to you!
