Last week and in pursuit of keeping the skin rashes at bay, I tried a new Dexcom sensor on my thigh, but instead of placing it directly against my skin, I put a piece of that Opsite Flexifix tape underneath the sensor (cutting a teeny hole out for the Dexcom wire insertion), and sticking the sensor to that instead of my actual skin.
And for the first few days, I was all, "Ahhhh!" because it seemed like it was a solution to avoiding the itchy, burning rash.
And then, I was all *scratch, scratch,* because the sensor was somehow affecting my skin, even with the tape as a barrier. I gave the site a full seven days, but as soon as it beeped "Change sensor now," I gratefully ripped the thing loose. Underneath, the rash wasn't too raw (not nearly as raw as the first one I experienced), but it was prickly and bumpy and if I let my brain think about how much it might possibly itch, I wanted to scratch my leg down to the bare bone.
So I'm trying two new attempts this week: the sensor is up north, on my arm, and I also applied a layer of Benadryl spray to my skin before slapping on the new sensor (per the recommendation of several very clever people, to whom I shall send balloons and jellybeans to). So far, since last night, not a whisper of an itch, and the sensor is giving me very good results. Will this work because of the Benadryl? Or because the sensor is in completely new skin real estate? Did I get a batch of sensors that I'm reacting strangely to?
Whatever works. Not having the Dexcom information makes me twitchy, so I'll tar and feather myself if that's what it takes to keep this thing stuck on and keep my safety net intact.
