I am going to see a new pulmonary doctor next month and what questions should I ask him? I am 96 years old, had whooping cough followed by diphtheria (?) when I was 6 weeks old. Noticed shortness of breath in 2008 while walking down a hallway. Since then have been on 2 % oxygen at night (Sleep Apnea), and on nebulizer when I think of it during day. I have other non-fatal medical issues. I have poor balance and it is hard for me to straighten up for fear of falling (have had a few plops this year). My feet have calluses which makes it hard to walk easily. Enough info? Lately, going upstairs to my room gets me huffing and puffing for a few minutes. Thank you for your input.
