Anne,
You are absolutely correct. No two people have FM in the same way. What works for one may not work for another.
Unfortunately, docs have the no narcotics stance with FM right now. While I refuse to be a guinea pig for pharma companies, I hope they come out with a pain med for FM that is effective and non-narcotic.
Until then, we all must do what we can to live through the days.

As for the rice/corn bags...I got mine off ebay. A lady makes them and you can choose the fabric and the type. I have one for my neck and shoulder area, but she also makes ones for other areas. Just look up corn bags in the search. They make great gifts and are very inexpensive.
