The heating pad the size of a electric blanket.

Last night my left side hurt pretty bad. The only thing that seemed to help it was a hot bath. I powered through the night and spent the rest of the day recovering. I finally feel better today and am ready to head back to work.

Buffy went to Walmart today and purchased a heating pad for me. I don't really need it right now but if my back starts to hurt I have it ready. I can literally wrap the pad around my entire back and both of my sides. So, is it a heating pad or electric blanket?
