Hi and welcome to the GERD forum.
Deff get to ur Dr for testing...the longer u have this condition and it is not treated correctly it can cause damage. The meds are there to help heal damage, so see the Dr to find which is the right med for u.
U will also have to modify ur diet and lifestyle and exercise....meds alone can not help this condition and if u have stress u will have to try to do things to relax.
In lifestyle tips, it is suggested u elevate the head of ur bed to have gravity help keep the acids down where they belong and out of ur mouth and throat.
See the health pages for foods that are safe and which ones to avoid-
