I also cannot sleep because of burning searing pain in my hip and down both legs from crps. I take temazepam every night and couldnt get any rest without it. Not sleeping makes me hurt everywhere. One thing that helped me deal with this when it first started was to reflect on my day and find something positive about it. Sometimes the best part of my day was something little like gee I'm glad the sun was out, or how great it felt to take a shower. Over time the positive moments get bigger n bigger, like wow i sat thru a movie and dont feel horrible. You are making some serious progress in phy therapy. Kudos for that.
