I hope you have had success in getting a resolution! My husband has experienced the very same issues and then some for over a year now. He had appt. with gastrologist today checking for GERD, scheduled for endoscopicthe end of this month. He has gone from pneumonia, Vtech ablation, COPD, Asthma, sinusitis, rhinitis, allergic reaction to silicates, Sinus polyp surgery, complete blood allergy tests, dysfunctional vocal chords, anxiety/panic attacks, high blood pressure, go figure he is anxious and desperate to figure out what is actually causing his breathing issues. Aleve three times a day tends to be the magic drug that gives him relief. Doctors all say that doesn't make sense and that can hurt your liver ..... but ya know what, it helps him to have a couple of hours of relief and somewhat normal life style.
Your Dr should go over it with u . Mine explained mine to me. Call and keep after it until he does
