So my pulmonologist said that my condition is ideopathic. He does not think I have IPF which is encouraging but no diagnosis is frustrating. Numbers are about the same with FEV 1 at 1.53/ 68%. Put me on 3ml with activity. Now opinion please we have scheduled trip to squaw Valley CA which has yellow to red AQ because of fires. Hate to wimp out but asking for some helpful input.
