I can relate to you. I had the same problem since 2020 when I contracted Covid. I drank so much liquid trying to wash it down. Coughing so hard my throat became so sore, it was hard to swallow. I was also getting alot of sinus and ear infections. After getting tired of steroids, antibiotics, variety of nasal sprays, I asked my PCP and Pulmonologist what else cold I do since the infections keep coming back so quickly. The suggested seeing an Allergist to see what I am allergic to and start allergy shots. While being tested for the multiple things, the doctor heard me coughing, and came in to talk to me.

After my exam and talking to me about symptoms, he suggested I see a Vocal Dr. He said he heard me straining to talk and my voice cracking. Come to find out, all my coughing strained my vocal cords. After meds from the Vocal Dr and finding out the long list of things I am allergic to, and starting allergy shots. The sinus draining, infections, coughing, and taking more multiple meds have stopped. I made it through the winter with just a little cold that did not last but a day or two.

You may need to see multiple specialist to find cause and relief. Don't give up stay strong and don't stop looking for relief.
