After doing test after test after test, and then did some more tests.
The pulmonologist diagnosed me with severe COPD.
I’m now on oxygen 24/7. I tried the other day to go without, that last about 15 minutes max. My O2 level dropped to around 86, and I couldn’t take it anymore, so I put the oxygen back on.
I took a bit for my level to come up. The doctor told me not to do that no more, that is when I learned a bit more, it seems that my lungs are only working at about 50% of normal.
