What did it for me was putting off getting a new bed. I knew my old one had a dip - heck, we'd bought these inflatable bladders to push the dip up. I knew it was making my back worse.
Then I got a new bed, and while my back was WAY better, that's when I realized I was hurting everywhere else. It was like taking away that one intense focus suddenly made it clear that it wasn't JUST my back. And that yes, my hands and feet really WERE that sore and stiff, and swollen feeling even if I hadn't been walking around or using my hands a whole lot the day before. And the fact that I've had to sleep with a pillow between my knees because it was excruciating for the inside of my knees to touch... and things just started to fall into place since my mom has had fibro for years.
