I don't know what a plug is...but I contracted RSV 2 yrs ago at a children's (large B-Day gathering).
It lasted 9 week - day and night coughing/lost voice/breathing REALL bad, should have gone to ER..but even doc wouldn't let me in the office. Then I had pneumonia and then black spot found on my right lung. NP diagnosed me with COPD; doc - said no it's ASTHMA. I am told now, the nodules are small on lung - but I cough up mucus and phlegm every morning and evening - it's disgusting. COPD disks are $400-$600 - it's a sad day - that we can't make breathing affordable.
