15 months ago I went thru a period of swallowing difficulty, dry cough, feeling like a lump in the throat, and heavy mucus
in the back of my throat. Went to see an ENT and he performed an endoscopy, I think (small tube with light into my nose and down my throat). Told me I had LPR, put me on 40mg Nexium a day. I took it for 3 months and things got better, but after being off it for a month or so, things were right back to where they were, but without the dry cough.
