Pam, I suffered three tragic accidents and developed chronic back pain. In muscle! It might sound simple but moist heat helped. I couldn't sleep like you have described. I went online to Thermal-On and ordered two moist heat pads which cover all my back at night. I put them in the Microwave and beep them 3 min. then sleep on warm moist heat all night. In the morning, pain is gone or subsided by half the amount I began with. I know this may not seem like much but I hope it helps. Later without so much pain, I could think and joined a Gentle Yoga class. It meets once a week. Slowly, Slowly after 3 years I've begun to heal and can now walk up to 5 blocks in the city.
My back is healing. In Gentle Yoga individuals stretch according to their own abilities. Yoga may not do the trick here if you are allergic to Insulin, but the moist heat will help I'm sure. With sleep you'll begin to feel better in general and be able to think better.
Good Luck , Cathy
