There's a big difference between a MG breathing pattern and a COPD one. Were the doctors being lazy? Possibly.
Request the results of both the X-rays and the breathing tests at the clinic. Portals only hold so much info. There are so many things that doctors do not tell patients!
If your MEP was bad the day of the X-ray, then maybe you couldn't get enough air out of the lungs. Duh, doctors. MG can cause an inability to inhale or exhale well enough.

You need a good pulmonologist who understands MG. You need to be thoroughly evaluated for what is truly going on. COPD is serious. And treatment is key to that progressing too quickly.
Please, get those records and have a new evaluation. Someone should be able to figure this out!
