I also have this problem and talked to my diabetic nurse about this, she suggested putting the sensor on my thigh to give my arms a rest and also to try Cavilon (I have tried SkinTac and SkinPrep neither of which worked). Has anyone else tried their sensor on their leg? Abbott say not to (I suspect because they haven't actually tested it anywhere else apart from the arm) but my nurse said there wasn't much of a difference in results. My sensors have also, within the last 3 weeks or so, stopped sticking (never used to have a problem), one fell off after 4 days, the next after 6 and the one I have on at the moment started coming unstuck a day or so ago and I have popped Tegaderm Transparent Film Dressing over it which so far appears to be doing the business - fingers crossed!! I am going to be little Ms Devastated if I have to stop using the Libre, my control is so much better:-(
