Hi and excuse me for butting in but, I live with heating pads and highly recommend the soft, pliable heating packs that are filled with buck wheat (or other stuff) and heat in the microwave. I have multiple and use them on my whole body. They even come to bed with me. They are life savers for my pain and best part yet...aren't drugs! Good luck.

It is a pad heated by electricity. You can use a a warm towel. Or a water bottle with warm water.
