Hi- I just completed my second z-pak for a sinus infection. My nasal congestion and sinus pressure have disappeared but I am still having throat drainage (white foamy if I spit it out), throat clearing, plugged ears, and some dry mouth with extra effort to swallow (no pain or difficulty getting food down... just more chewing and effort). I realize the chewing and swallowing may be because I am anxious about something more sinister like throat cancer. When I use any of the online tools and type in my symptoms, lpr (silent reflux) come up? Should I bring this up with my Dr?
