Looking for insight
48 soon 49 female smiker. last year and a half I had alot of stress was fatigue everyday I would here myself awake when falling asleep they said panic attacks. I started taking my oxygen when I would wake ut was in the 80s U went for a sleep test they said I hadn't had enough episodes to be apnea that was a year ago maybe a bit longer year and 3 months. Still feeling extreme fatigue my dr done an overnight pulse ox it was showing 70s she sends me to a pulmonologist who does all the standard tests everything checks out except im retaining mild carbon smoker. She sends ne for a other sleep test the respitory therapist their said I was living in the 70 the pulmonologist said I drop their in rem sleep. She doesn't offer cpap but wants me to go on oxygen at night. I read that thats usually not the treatment. Then she has the nurse follow me into the parking lot and say I may not for sure have a very mild cause of emphysema I said how do we k ow if I do the nurse said x rays but the pulmonologist said my x ray was good. Any advice would be helpful. For reference my oxygen only goes down when im sleeping it goes up when im exxersing.
