I feel for you. Been in the situation for other reasons. It really really sucks, try sitting in a cool not cold very dark room and try to relax. Even if you don't sleep this wil help to rest you mind and body.
If you need distraction from the pain, read or watch a movie laying in a comfortabe, dark place. Reading is better than tv because of the stimulation of color and lights. Try to get into a good light read. An easy, exciting book in bed, in a cool room, in the blankets, with the lights off and a reading lamp on is a way to rest when you can't sleep- even in the middle of the day.
I hope you get some sleep soon. For me it is a way to excape pain when I medication isn't doung enough.
