I am a black female, fifty-six years of age, 5ft 3' and approximately 180 lbs. Occasionally I have a sinus infection. I am taking 1.5 mg Natrilix daily for hypertension and 10 mg Crestor for cholesterol. Over the past three weeks I have had an irritating cough which my doctor attributes to a sinus drip. Today, I started having a bubbly feeling in the center of my chest, somewhere between my breasts. When it happens, I am forced to cough nd there is a feeling as if I am not getting enough oxygen.
