Don't think I have seen this one posted here, but rather than a heating pad which can get too hot, and a heated washcloth which can lose heat quickly, it you take some dry, uncooked rice and heat it for about 15-20 seconds in the microwave in a ziplock bag (I leave the bag unzipped until I am done heating) then wrap it in a washcloth, you have a heat source which will hold the heat for two + hours, and when it cools will not feel cold (like the washcloth will). It is almost free, and readily available in most houses (great if you are on vacation or visiting people). -Anne [Posted in FML issue 2539]
