First let me say welcome! There are many people here that are sometime more knowledgeable than doctors when it comes to CRPS.

I am also a WC case so I can relate when it comes to that. They originally paid for all of my treatments and medication, until I had to undergo more expensive treatments. When that happened they decided that the CRPS was not caused by the injury and they should not be held responsible. The majority of WC companies will do whatever they can to pay the smallest amount possible.

As far as the sleep issue goes I have found what works for one person may not work for you. Personally I find meditation to work for me most nights. I also find keeping to a routine can help as well. Some other things that work for me are chamomile tea and melatonin, with Benedryl being a last resort. Of course check with your doctor before taking any medication.

Good luck!
