I have been undergoing all sorts of testing and so far not a lot of
answers. I am on oxygen at home and also started using a
CPAP machine this past December. I am 53, female, x-smoker, never ever any serious lung issues in the past. Hospitalized twice since Valentines Day. Minor heart , Major Lung! Have not actually been handed COPD Dx as of yet, but it has been suggested. I am suffering with this tightness in my chest. I am wondering if CPAP or Oxygen level is making me worse?
