Just in case someone has a Dexcom Rash and needs ideas, there is a Facebook group called Dexcom Rash that has different ways people have solved this. My younger one tried on and off since 2008 to wear Dexcom. SO from Navigator to Dexcom back to Navigator to Enlite. We are finally back on Dexcom. Nice having both kids on the same sensor. It was not until last year we used Flonase and Tough Pad together. It solved our problems.
