Hi Karen,
My doctor suggested that I listen to Mindfulness Meditation for Pain Relief by Jon Kabat-Zinn. I'm not really one for meditation stuff, but I've been listening to it for the last week when I go to bed and its the first time in 4 months (that's how long I've had CRPS) that I've slept through the night. It's only $13 on amazon and $11 to download on his site so it might be worth a try. I hope you get some sleep!
