Heathert. I was diagnosed with bronchiectasis and Mac about 5 years ago after a cat scan for a possibly perforated esophagus. I had been coughing and short of breath for a year or so, which was attributed to post nasal drip and my afib. As far as the allergies go, I’ve had them for many years ...well before I was diagnosed with Mac. Especially have trouble in large gatherings when people wear colognes. I also have sensitivities to foods and many antibiotics. I use fragrance free everything...soaps, detergents, and all natural clothing and bedding. Unfortunately, my condo has carpeting in the bedrooms and it is a costly proposition to put in hardwood floors. Won’t be doing that for awhile.
