I Have GERD Issues Which Has Caused My Larynx To

I have GERD issues which has caused my larynx to become swallen and this in turn is causing me to be SOB, Wheezy, and some congention in the throat. What can I do to clear this up? I am watching what I eat but have not been able to clear myself of this issue. Been to a ENT doctor also a Pulmonary doctor. Been on inhalers which don't help me. Steriods medicine, anacides. my next step is to see a gastrologist.
