I'm 80 years young now...... and I first went to Mayo's in Rochester 7 years ago. It is certainly worth your time. They diagnosed me there within an hour and set me up with a pulmonologist who I feel has been very kind, thoughtful, and has good answers. He's Teng Moua. I've been to see him only 3 times over the years but he's great with emails directed to him. There's never a charge for any correspondence with him or help from him in any way. I'm in Kansas so it's a 12 hour drive....... I can have a cat scan or sputum test done at a local lab and sent to him. He will respond with his opinion and recommendations from that. I feel I need to go back up there before long but the pandemic has kept me from wanting to be in crowds these days. But..... I'm planning to do so this coming year. I hope you will give them a try. I do feel you will come away feeling much better than before your trip. Let us know what you do and how you feel about them. Jan
