I have had a cough since covid in late 2020. I went to an allergist due to constant sinus and ear infections since covid. He witnessed my cough, clearing my throat, and asked questions. I told him I went to an ENT several times, but he never scoped my sinus and throat. He referred me to another ENT with IU Medical. She asked about my cough. What triggered it, what helped, does my voice change. After performing a scope procedure, she showed me pictures of my vocal cords. One was shorter and inflamed. She believed my severe GERD, Hiatal Hernia, infections, and coughing for over 3 years, that it affected my right vocal cord. Which is where I feel like something is caught in my throat.

I had been one both medications in the past, but separately. She suggested I take them together and slowly progress to the highest dose until she saw me 6 weeks later. My cough has improved greatly. My next scoped showed the vocal cord recovering and we began reducing the meds. I hope this will help you in areas to look.
