I can t get to the bottom of this. 1st I think it s a milk allergy...then a gluten allergy. It seems everything I eat causes me this symptom which is quite a problem. It is the feeling that I have something behind my nose or in my throat. My breathing is fine and not obstructed. But I always feel I have maybe thick mucus that I can t get rid of. I use a neti pot every morning at least 5X in each nostril. I ll feel better for a while but the feeling in my throat and in my rt cheek sinus comes and goes. Comes more than goes.
