Could This be LPR?

I'm 37 andI just had my tonsils and adenoids (adenoids) out 2 months ago and it did not help my problem.  I still have a sore throat, that is dry, burns and pinches and ear pain with no infection. My ENT released me and said it has nothing to do with my tonsils and that I should go to an endocrinologist, immunologist or infectious disease dr. I always have excess mucous and a feeling that there is a lump in my throat I can not swallow.  I am constantly sick with upper respiratory and sinus infections and exhausted beyond normal along with a constant achy sore body.  My son's speech pathologist says it sounds like lpr, but could it cause illnesses and fatigue and a sore body.  I am going to an infectious disease dr. this week because I have no options left.
