8 months Pregnant and can't sleep. Need help finding a way to sleep.

I need help finding a way to sleep at night. I am 8 months pregnant and have had back pain and belly discomfort while sleeping. I am usually tired all day, feeling like I had no sleep. I wake up at least every hour from the pain. I also have the carpel tunnel syndrome where left arm/hand is numb and right arm/hand is in pain through out the night. I could use some advice on how to get some sleep…
