I use a tape called Hypafix as well as skin prep. Apply the senser to the tape and then apply and insert thru the tape. Worked wonders for me. I have not had any issues since I started using these. Amazon
I would suggest moisturising it with an ointment even vasoline. Can you wear gloves at work. Maybe put a gauze around it and tape it with hypafix while you are working.
