I just had first visit with pulmo doc and going to have another cat scan. Feeling more energetic now , try to go to water aerobics every morning, can do this better then walking ???? how did you get on research program at Mayo, we have mayo here and I sure would like to get in a program for the medication is too expensive for me. Praying that nodules in lung has not grown. I also had diagnoses of IPF in 2013, but they said I was ok after medication treatment, wondering if I still had this all these years, slow growing if so. Thanks for caring and keep me posted.
