I had told my pulmonologist that at times my pulse ox is reading 90 or one time 88 at rest. I've given up exercise. I asked him about this and he said not to worry unless it drops into the 70s and I'm having a hard time? That doesn't sound like sound advice to me. I haven't been the same since my flare last October and have gone from being very active with exercise, yardwork, extensive landscaping work I did and all kinds of activities including kayak fishing. Now I've become a recluse. Getting ct scan of lungs and echocardiagram on Thursday idk
