I'm not sure what they are called. I can't remember(fibro fog) where I heard about it. I think it is a pillow filled with beans(or something similar). You put it in the microwave to make it warm, & then you can put it anywhere on your body to help with the pain. I don't have insurance-so no pain meds. I use a heating pad, but it's not flexible enough; & I need it for my back & front & limbs all at the same time. Plus it's not safe to use a heating pad in bed. Depending on the expense, I thought I could get more than one.
PLEASE, IF ANYONE KNOWS, EMAIL ME.
THANK YOU IN ADVANCE.
