I'm sorry you're having those issues. CGMs can have their problems. My doctor said false low readings is a common problem reported with both Dexcom and Freestyle Libre.
I have problems with my Freestyle Libre giving me false low readings but only on my left arm intermittently. I wasted 2 sensors figuring out the problem when I was getting obviously constant false low readings. Between Abbot my doctor and my own experimenting it was determined after I had experienced an extreme weight loss the subcutaneous tissue in that area of my arm had thinned out too much for the sensor to work reliably. I have since only installed sensors on my right arm even though I've regained the weight and more. I now have a fear of wasting expensive sensors. Because of my experimenting I had to purchase extra sensors online for about $100 a piece. That's my copay for 6-7 sensors depending on which month the is fulfilled.

@Justmeraeagain Yup I know Dexcom is a little less expensive than Freestyle but this is the unit Humana supplies it's not like I have a choice. I am however surprised they haven't upgraded me to the Libre 3. When I was using meters they kept me updated with the newest model. Aetna did the same when I had insurance through my employer before I went on Medicare.
