Xyrem changed my life for 10 years, made me have almost no pain, didn't feel like a train had run over me every morning, but now, due to FDA, doc refuses to prescribe it!
Stretching exercises, ideally every day; long walks when possible; swimming in the Y lap-pool (cool temp really helps pain!), general exercise when I can tolerate it, the spa and steam room; when I can afford it a massage.
