Best way to sleep with a neck and back pinched nerve, can't fall asleep.

Buckwheat pillow: can help. Like a bean bag chair it holds its shape better than a chiropractic pillow. Plus moisture cause the buckwheat to deform creating air channels. This keeps the pillow nice and cool. I used one when I hurt my neck playing volley ball. The downside is they are quite heavy. (you'll want to take it on the plane if you travel) I recommend getting a new mattress for the back (firm memory foam)
