Last night I took out sensor 14. It was working fine, but it was itching fierce, possibly because the adhesive was off enough that the sensor was probably able to move a bit.
I took a bath, I put in sensor 15. It was the first sensor that I put in all by my self, and I'm kinda proud of it. It's in my right arm. It was giving kind of weird numbers, had some ???s overnight and in the morning, then seemed to be settling down to something like accuracy.
Around noon, it made a little beep sound. One single beep. I pressed a button, it didn't turn on, so I held down all the buttons until it said Initializing... and it started back up again (with readings).
It gave a beep and did that again around 2:30. It did again at 4:00. At 4:15 I heard a beep and looking down and it said Initializing... and then it said Err with a triangle, and the code HWRFT. I called Dexcom, they said it's a hardware error, and I should have a new Dexcom tomorrow by 4:30.
So I'm leaving the sensor in and will "start" it tomorrow after I get home from work. I really want to have a working sensor for Wednesday's endoscopy day.
So in case you wondered what the death knell sounds like... it's a single high pitched beeep.
