This is what I bought. I like the heating pad but I'm constantly fighting with it and you're really not supposed to fall asleep with it on, as it can cause severe burns. My mom works for a surgery center that does a lot of chronic pain patients who often come in with burns. This stays hot for a couple hours, and it makes me feel better.

I always wear wool socks on my feet and it helps a lot with my feet. I had an electric hand warmer from Amazon, but I lost it when I moved. I like to use a hot water bottle hand warmer that straps around the waist at home for my hands.
