You may all want to google gaslighting. It is about docs. Health care is lax today in many areas; it isn't all the doc's fault as corporations own these places where they work and it's about money. My doc actually told me they didn't make enough money on me to run a test. Be your own doc. Do as much research as you can. When you see a doc, go in with the facts and what you want.

Exercise makes a huge difference. I started approximately a year ago and it has been a life saver for me I am not oxygen dependent but I do have severe shortage of breath it's probably the worst feeling in the world I think of every step I take before I take it I'm trying to learn to live with things the way they need to be and be grateful for the things in life that I love and enjoy it certainly makes us think about our priorities

Unfortunately most doctors today are just assembly line workers who have a medical degree. Went for my annual " complete " physical about a month ago and my Doctor was in and out the door in about 5 minutes. Have had tons of questions for my respiratory doctor that still go unanswered and I have caught him in a couple of lies. All we can do is take it one day at a time and try to manage the COPD ourselves. Sometimes I think it's the medications that make it worse.

Mary, I would do as others have sugested, get a second opinion. I too found out that I needed to see a cardiologist about my heart because with COPD your heart is working harder keep your oxygen flowing as well as your blood. This is not uncommon for those of us with breathing issues. Take care, breathe easy, go see a different dr. and God Bless you.
