For all of us out there who use heating pads here is what I was told by a
nurse to do to avoid the red burn like marks from using them constantly:
1) put a moist wash cloth between the heating pad and the heating pad cover
That also helps the pain as well as avoids the burn marks
2) If you are afraid of using the moist heat, wrap the heating pad itself in
a towel and then put the cover over that.
3) Apply lotion on the area where the heating pad is going to be.
I've tried all these methods and they all work for me and I use a heating
pad 24/7 on high and have gone through atleast 6 heating pads in a year LOL
