Hi Gabriel, I have a question for you. Doesn't singing make your breathing problem worse? Because if I sing a little, this breathing problem becomes more severe. Maybe stomach acid has damaged the larynx for a long time and this tension is to compensate for the damage. If you can go to a laryngologist and describe your problem completely and take a picture of the larynx. Maybe where you are, doctors will have more knowledge and the root cause will be discovered

I took another picture of my larynx. The doctor told me that you have laryngeal muscle tension, but it is not severe. He said that you should see a speech therapist. I went but it didn't work. Some speech therapists suggested laryngeal massage, but I massaged my own larynx. When I moved my larynx left and right, my breathing problems got worse and my voice got better. I decided not to use my larynx for a while, that is, not to sing and only to speak normally occasionally. Normal talking helped a little, although I had difficulty breathing deeply and yawning, but it was more tolerable. Now, if I sing again, this problem becomes severe, but normal speech does not cause a problem. I had a good voice, but I could not raise and lower my voice like other singers, and if I try for this, the yawning and shortness of breath will intensify, I think This laryngeal muscle tension is formed to protect the trachea from acid. What do you think?

Next I want to see a stomach specialist and do some tests. I definitely know I have lpr but I want to check more closely
