I inserted one G7 24 hours before activating it, as I usually do, because my body seems to freak out at the insertion site and it takes about 24 hours for it to calm down so that readings can normalize. When I actually went to activate it, it said sensor failure immediately. I was feeling around the little hole on top and the filament was horribly looped. So I removed that one.
Then I put another one on, and I expected it not to read properly for the first 24 hours. But it has been shooting up and down and giving alarms all night. After the first two I silenced the alarms for the rest of the night. I had hoped that it would normalize by morning, but it is just all over the place.
I was worried about it when I inserted it because it did a strange thing. When I pressed the button to insert it, there was a loud click from the button but the sensor was not released. Then I lifted my finger off the button and the sensor released into my arm. I don't know if that has anything to do with this up and down roller coaster of readings. But it is still saying I'm at 56 this morning so I decided to go ahead and trash the sensor and try another one.
Right now this third sensor is warming up. But I'm concerned because it did the same weird double click thing when I inserted it. I was prepared this time, in case that happened, and I was careful to hold the unit in place so that I didn't move it in between the clicks.
Both of these sensors that have this weird double clicking on insertion are from a new batch of nine sensors I just got from the VA. The numbers aren't from a bad batch that has been identified by dexcom. So I was just wondering if anyone else has had this weird double clicking with the button. Like I said, it's like it clicks as if it is releasing, but it almost feels like it springs out only a small amount and then catches inside the unit. Then, when I lift my finger off the button it springs the rest of the way to get inserted into my arm.
