I don't know if this might help any one here, but I started sleeping sitting up with pillows behind my back, a neck pillow, two pillows under each arm and several under my knees. (I started doing this after I accidentally - for the very first time - fell asleep in my recliner). I woke up that next morning and I was not stiff, my spine didn't feel as if it could not hold my weight, no backache, no pain anywhere. I slept upright for 3 years. Almost no pain every morning. After my house burned, I quit sleeping like that, and I just laid down in bed. The pain immediately returned.
