You think the sensor is not giving you the right numbers because it measures a different fluid. It will be approx. 15 minutes or so behind a finger stick, so if you need to know exactly what it is at the moment, do a finger stick. With the Libre 3 you don't have to touch the reader to the sensor, just push the button on the reader and it tells you what your BG is. But it too, is going to be a little behind reality. It has nothing to do with where the sensor is placed as long as it is placed where the directions state. It's your life so I would do what the manufacturers say. I'm still in pain, damn it!!! But thanks for caring.
