Dexcom Innaccurate to a large degree?

thanks Michael,

did you do this on the outside of your thigh or the inside? I think the outside would be much less painful, the inner thigh is too sensitive. I found this image of one on the outer arm where the fat is, I do have fat there but it's also closer to the muscle and that needle is quite large.

I also have a rash now from the latex I think or the adhesive, I'm not sure what is in that, so I'm going to need to do a barrier thing too, can I get those at a pharmacy? I really can't believe medical devices have anything latex in them anymore.

I'm glad this is working for you now... I'm going to try either my arm or my thy later and see what happens and I will post my results :)

I placed the sensor on the top of my thigh as if sitting in a chair. Imagine having your hands in your front pocket the sensor would be in the very center of the front pocket. I found the barriers, skin-tac, and flexfix at American Diabetes Wholesale. Ordered them online:)

Thanks Michael,

I put another sensor in my arm last night, but it was an ordeal- I couldn't get the needle out at first and I then couldn't get that part off the sensor base- I had to get help and it took about 20 minutes to do it- I thought I was going to have to go to the er or sleep with the whole kit and caboodle on me all night.

I have been having pain again ever since the sensor was in, I had to take a non tylenol pain killer and I'm sure now this isn't for me... I really don't understand how anyone can stand to have this thing in them 24/7- I am just too sensitive.

Again the readings have been wildly inaccurate, it kept waking me up and telling me I was in the 50's and 40's and I knew I wasn't, it just said that now and I tested at 71, that one is closer than the previous sensors readings but it is still a huge difference- I would not take G tabs at 71 but at 51 I would.

So I am giving up now, I am going to leave this sensor in as long as I can stand it to see if it gets more accurate. I don't know- maybe I should just remove it since I'm probably getting more inflammation again. The spot on my stomach is getting better but it's still sore to the touch. I had decided not to use my legs as a site due to having a dvt in left leg and symptoms in my right leg- I was afraid I could hit possibly hit a vein and affect my circulation. I did put a tegaderm patch under this one so hopefully I won't get a rash.

It should not hurt like that. I wonder if it is in muscle instead of fat ?

I agree, I've never had one hurt. Sometimes I have to feel around on my body to remember where it is LOL

I don't know how to tell if it is in a muscle for sure.. here is an image![|373x480](upload://2YYHheyPHSYXYigzMDCh8BCgGll.jpeg)
- I placed it horizontally instead of vertically and I wonder if that was a bad idea.. I do have a good amount of fat in this area and it seemed like a good spot.

wow... that is good... I wish that was the case for me... I have felt pain instantly with both sensors.

I feel this pinching feeling all the time when I move around and I can feel it all the time... I would never forget it's there or need to look for it.

Nothing is more frustrating when the sensor is unfconfortble and gives false readings. It seems to create a love/ hate relationship for all of us. IT DOES TAKE TIME! If you can find 1 or 2 spots tht work , that would be enough. I have started wearing it for a week or 2 , then taking a few weeks off, then putting one on if needed. As for your site...the back flabby part of arm may be better choice. love handle area even if you do not have much flab there. Good luck!

Meee, one of the reasons I have started using the thigh area, is because I can visually see the insertion point and can adjust the angle of the inserter so as to keep the sensor needle shallow, just under the skin.
This area gives me good visibility and keeps both hands free, I can pinch up a good bit of skin, angle the inserter to match the angle/fall of the flesh and press the inserter quickly.
The only discomfort was the initial pinch, I will say the first sensor in my abdomen just plain hurt, when I placed it, when I tried to sleep the first two nights, every time I bent over, everytime I twisted my upper torso. I dealt with it until the itching started after 4 days, and would not quit.
My second sensor went in my right leg/thigh, I had it angled too deeply and every once in a while I would feel the pinch of the sensor press against the muscle, this hurts. The pain from this would worsen as I rode my bike, because I would lose water weight as I rode causing the sensor to touch the muscle more.
It seems as keeping the sensor needle shallow has been the trick, I am still using the sensor I placed 11 days ago, and the reading was off this morning, my dex, said 95 and my one touch said 94 this a.m.:)
Please don't give up Meee, I know I wanted to drive over my dex with my Jeep repeatedly with the first two sensors, but once I have figured it out, I would not want to be without it for very long.
I did take a break between sensor 1 and 2, while waiting on the barrier material, and then again between sensor 2 and 3 waiting on the skin-tac. This helped me mentally and made it easier, and helped me to realize I could take a break whenever I felt I needed to.

Meee - everything I’ve read and heard is that the sensor should be in line with the limb if it’s not on the abdomen. The best spot I’ve found for me so far is if you rotated that position to vertical at the left edge of the tape. A little above the triceps and right to the back side of the deltoid if you know your muscles.



I wish you better luck in finding a good spot, because like others have stated, I hardly even notice it and it certainly doesn’t cause any pain.

thanks everyone,

I'm not sure what to do- I've still had mostly inaccurate readings... this past 6am dex = 169 my meter = 53! I had to take sugar, fortunately I usually wake up when I'm low while sleeping.

There have only been 3 or so readings on this sensor which were dead on and the trends are sometimes wrong- I went for a walk after an after meal spike and it said I went up to 200 during the walk, but when I returned I was 93 according to my meter and I was only walking for 20 minutes or so so I don't think I would have dropped that much.

I did discover though yesterday that I had spiked to 130 when dex asked for a blood test- that is higher than I have ever gone as far as I know since my new diet and I'm not sure why- it happened again tonight -

I think both my pens were too old and I've changed them now but I'm not sure if this was the cause or if it's still instability from dka or something else. The diabetic educator thought I should maybe return it as it is too inaccurate.

Im so tired... and it still hurts, so it doesn't seem worth it, I think I need a much smaller sensor and more accuracy to make this worth it for me. It's such an ordeal to get this thing in me- I don't think I can get it vertically on the back of my arm without help and I'm not sure where all the muscles are and so on. I'll see how I feel about it tomorrow... but I wonder if having this sensor in me could spike my sugars also, maybe the fact that I'm having discomfort from it could have that effect on me.
