I would certainly inform your doc that you suspect GERD and have him start you on some medication (an H2-blocker or a PPI). Leaving GERD/acid reflux untreated can lead to more serious conditions. If your doc doesn't follow through, see another doctor, preferable a ENT (Ear, Nose, Throat) doctor.
Also keep in mind that PPI's are stronger than H2-blockers and in both categories there are several to choose from. If one does not work for you, another one will.
Come back here and let us know what your doc recommended and how you're doing
