So Im changing my infusion set this morning and my Dexcom sensor expired 2 hours ago so I restarted it. No big deal right? Yeah I yank my set and there is a spec of puss in it. Not so great but its not like thats never happened. Put a new set in get it all hooked up and Dex is ready to calibrate. Ok great! Not great. My blood sugar is 500 and I had no clue besides my stomach feels kinda crappy. This is why my Dexcom is so so very important. I had no idea I was 500! I mean come on holy crap 500!!!!! Freakn wnderful. So I just took a giant correction and now I cant calibrate Dex until Im under 400 since you cant enter a number over 400. Great way to start the day. Now I feel like barfing and I have to drink a ton of water.
