I am going to bet that you have the same thing my ENT diagnosed me with. It is a type of acid reflux that affects the throat and voice box, and the only symptom I have is a lump in my throat. So you can research it, the name is laryngopharyngeal reflux. I am on 40mg of Prilosec twice a day, an hour before breakfast and dinner. I still have the lump in my throat, so I am assuming at my next ENT appt he will be sending me for an endoscopy.
I have had the lump in the throat feeling for approx 5 weeks now. I am trying my best to not let it drive me crazy. I finally went to an ENT doctor and she told me it was acid reflux. I was shocked, because I have no other symptoms. I do not eat spicy foods, I rarely have burning or indegestion. She said it could be brought on by smoking and drinking coke. She put me on medicine. I am going to try on of the cures I found on this site... Apple cider vinegar, baking soda, water solution; or just a plain apple before bed. I do not like taking medicine daily. The cost with insurance is $25. a month for the nexium.
