I was wondering if anyone had any info. about acid reflux and a burning in the throat along with always seeming the need to clear mucos out of your throat.

All too common. People who suffer this continuously seem to have specifically laryngopharyngeal reflux disease (LPRD), which is reflux affecting mainly the throat/mouth, little of any other typical "acid-reflux" (gastroesophageal reflux, GERD) symptoms, and are better lying down asleep than being awake (reverse of GERD).

In any case, these symptoms are frequently listed under GERD symptoms.

I have an incessantly warm throat, which is often scratchy or "burning" or even sore. Also I have the sensation of lots of phlegm - which I've always had, as a sinus sufferer, but this is different - lower down in my throat than normal, and more liquidy. So yes, I clear my throat alot because of the "phlegm".
