Thanks so much for your reply. I do have a newer, oversized heating pad that shuts off automaticly. However, I just switch it right back on.
I have it on most of the day. My husband keeps mentioning how my back looks from the discoloration. I know it can't be a good thing to do, but it helps so much with my back pain. Thankfully, I am not diabetic.
I was really just wondering if it might cook your insides or other kinds of things. Could the electrical currents cause problems? I need to do more research.
Thanks again angel!!!!
