The main symptoms were originally burning in the chest/sternum, regurgitating acid into to throat, burning between the shoulder blades, and constant belching.
More recently these symptoms increased to include a thick coating of phlegm
in the mouth, and a thick, heavy, mass of mucus in the back of my throat. The latter makes swallowing uneasy, and panics me sometimes that I can't breath.
I went to the doctor who prescribed me the PPI Protium (Protonix in the US).
