I spent a few days in the hospital recently. June 16 I was having so many problems with my oxygen levels that getting a glass of water downstairs walking 25 feet had me dropping. I had jumped also to 6 liters of oxygen for sleeping and showering & was really upset.
Something before had kind of felt off but I didn’t feel sick except for a day here or there. I just chalked it up to heat, humidity & bad breathing. There were days it was so bad I couldn’t even really talk much at all.
