For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (, which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

Yes, I've had red marks where the sensor holder has dug into my skin. They haven't actually been sores, but have taken a while to go away, so they seem to just be injured blood vessels. I don't have any good solutions to that problem, but for me, they're more of a nuisance than anything else.

Does anyone have the problem of the sharp prongs at the back and underneath of the sensor digging in to the skin and giving two small sores underneath I also scar from it it happen's more when I turn over in my sleep and and put pressure on it.

That's helpful to know! Thanks Clare!

Until the day my transmitter finally gave me the "low battery order new transmitter" warning, my battery status was always OK

Comment by Anthony on July 1, 2014 at 3:51pm
So for those that have had the TRANSMITTER die or about to die has anyone checked the battery status section on the receiver? It's under Settings then Device Info. What does it report for transmitter battery level?
Comment by Clare on July 1, 2014 at 2:48pm

To be honest, I have not had a receiver die yet. I have had 4 different receivers since I got the system in Nov. 2012. The first one I returned after a bit more than a month because the USB door fell off. The second one I used for almost a year but the USB port fell into the receiver body, Dexcom replaced that one. The next one I had a failure to communicate and failure to charge one day when I plugged it into the computer. The message was "USB device failure, replace device". So I called Dexcom and they replaced the device but this time insurance was charged because it had been more than a year since I had gotten it so I was not required to return it to them. Someone here recommended I attempt to reset my receiver using the pin hole on the back of it. So I did that and lo and behold it came back to life and started charging and downloading again. So now I have 2 receivers which both work. The manual is not very specific about receiver death so it's not very helpful on this topic.

I screwed up on my question, so I'll repeat it, and get the words right this time, LOL!! How do you know when your RECEIVER is dying?

Comment by Clare on July 1, 2014 at 10:13am

I just used a couple of zip ties through the holes to attach it. I have a padded case as well for my phone and bike tools but I like to have the receiver in easy view. I did 43 miles last weekend and with a 75% basal reduction and some stops along the way for sport beans and hydration I managed to maintain within my target range of 70-150. The beer and food at the end was definitely the highlight.
