Well, Jacob hasn't used his CGM is quite some time. We had problems with the Dex; he was allergic to the adhesive. He also breaks out from both Skin Tac and Mastisol. He breaks out from over bandages and they don't tend to stick very well, including Opsite. The edges curl up and he starts scratching within a couple of days. Now we have the Revel. The sites don't stick. The only thing I can really prep with is alcohol. Even if the site kind of sticks I still have to put tape or Opsite or something over the top. Those don't stick well either and then he breaks out. Getting three days would be very good and even then it all would be coming loose. Tonight I tried to insert a sensor and all that happened was that the part with the probe didn't stick hardly at all, then blood got under it and it was completely loose. The bottom part stuck a little but pulled off very easily. So no sensor. AGAIN. Any help would sure be appreciated. What HAVEN'T I thought of?
