Lori, I understand your worry. My dad died from esophageal cancer so of course I have concern.
Please read The Chronic Cough Enigma by Dr. Jamie Koufman. Even if you don’t have a cough, the book addresses voice changes and sore throat.

I am using many homeopathic remedies, but please do your own research if you decide to implement them.

Aloe Vera (ingested)
DGL
Zinc Carnosine
Teas with marshmallow root, slippery elm and licorice

If your doctor approves you can also investigate an H2 blocker like Pepcid. It is many times recommended for LPR.

Since I have had throat irritation for two and a half years, I finally found a doctor who could perform TNE-transnasal esophagocopy. This was a simple in office test where this ENT specialist was able to look down my throat with a camera. I have had two endoscopies in the past two years, but this was specific to the larynx and surrounding areas and required nor sedation.

Best wishes, Cindy
