First, I know they are other discussions regarding arm placement for the Dexcom, but none specifically addressed my issue, so I apologize but I am not intentionalyl clogging up the discussion board.
I've read a lot about alternate sites for the Dexcom sensor, and after 2 stomach sites I have opted to try the arm. I attached a picture on how I inserted it. I've seen many pictures online of how it should look and I think I may have "flipped it." Mine it still UP AND DOWN, but seems like it's UPSIDE DOWN compared to other peoples. Maybe this is causing my problems....
Anyhow, I have had EXCELLENT readings throughout the day. All readings have been between 1-10 points off - truly top notch. The problem is at night. Whenever I lay down (I avoid laying on the sensor), I shortly get the ??? error. Now, it is possible that I roll over on my side once I doze off and put pressure on the sensor, but even in the beginning of the night, before I fall asleep it does this.
It happened last night shortly after dinner before I even went to bed, then came back briefly before I laid down, then the ???'s came right back and lasted all night. It takes about 30 minutes to an 1 hour to come back from the ???. However, two nights in a row, it has lasted all night, and the graph shows reading's ending shortly after I went to bed.
Any suggestions? I don't think its the sensor because it has been top notch during the day. However, it IS a new sensor - it was inserted on Wednesday evening. As of right now, the sensor is about 1.5 days old.
Do any other arm wearers experiences this (or a similar) problem at night?
