Hi and thanks for using the forum.
You mention that the ENT noted your tonsils and adenoids were large, did he say they were unusually large? GERD and acid reflux can cause these symptoms, but usually you feel some pain (burning, etc.) as well. GERD and reflux also tend to be worse at night, whereas your symptoms don't seem to bother you at night. I would follow up with the ENT about the tonsils/adenoids and find out about that. IF the ENT clears you, then you could also have your thyroid checked to make sure it is not enlarged. THis can sometimes give you that "somthing in my throat" feeling. Hope this helps.
You could try looking up LPRD. It's a type or reflux but affects the throat and voice box.
I would think that stress may be a contributing factor.
Elevating the head of your bed by putting books under that end may help. Medication may also help if it is reflux, etc.
i had blood tests done and thyroid levels were fine. also had an ultrasound of the entire neck area and no thyroid issues were found. i just went to the dr yeaterday and he said that my tonsils were not as large as the ENT thought. He thinks it may be allergies.
