My symptoms have improved slightly with the control of stomach problems. I recently found out I have had silent reflux for a long time. I haven't done many tests for my stomach yet, but I plan to do it. But before that, I went to several ENT specialists and the photos of my larynx always showed stomach acid, but they confirmed the health of my larynx. Some of them suggested that I go to a speech therapist. I think it may be the main problem of the stomach that has disturbed the diaphragm, but maybe some speech therapist techniques can help. I also take anti-allergy pills and a history of I have allergies, but my lungs are completely healthy. I have little suspicion of laryngeal problems. A healthy voice is a sign of laryngeal health. Do you have a normal voice?
