I have been using the Freestyle Libre for 2 years now. Starting in Jan. 2020 I have had very low readings, 50-60mg/dl but when I check my blood glucose I am normal at 110 to 120 mg/dl. This is Not around eating. This is even when I first wake in the am. I have autoimmune Rheumatoid Arthritis and I wonder if something else could be blocking my interstitial tissue levels? I have not been able to reach anyone from Abbott that can transfer me to someone with a working knowledge of interference. Does anyone else have this problem and if so do you know why? Thanks!
