A couple days ago, I smelled smoke. I thought it was my laptop, because that was where the smoke seemed to be coming from. After unplugging my laptop and setting it outside, the smoke smell became worse. Thankfully, I rechecked and discovered what you see above. I had been using my heating pads constantly and rotating them over my body. This is one of the only things that soothes my pain. My lower back was bothering me that morning and so the heating pad ended up shoved partially into the couch cushion. My couch must have fire retardant on it, because it did not have any black marks. Now, I only have one heating pad and I’m afraid to use it. If you use a heating pad, follow the directions printed on the cloth cover. Make sure you are not bending the cord and turn the heating pad off or unplug when not in use. This one had an automatic shut-off of 2 hours and nothing on it felt hot when I left it plugged in. However, my other heating pad, even though it had an automatic shut-off of 1 hour, had a red light that would stay lit to let you know it was off. I noticed that the control box was often hot when I left it plugged in, even though the actual pad wasn’t on. It is scary to think what could have happened, had I not been home when this occurred. I always left my heating pads plugged in, because, if I was sitting down, I was using them.
