That’s funny...that is what I first thought this thread was about...on the back, side, etc.
When I go to sleep, I often start out on my back with my arms over my head. I have no idea why, but that is what is most comfortable. Then I end up on my sides like old Dagwood there.
I hurt (aggravated) my back recently, and somehow ended up on my stomach, and...I couldn’t get off of my stomach, the pain was excruciating when I tried to roll to one side or the other. Eventually I did it, but...that was a new one for me.
I fell off the roof 2 yrs ago and got TBI. Still have a balne problem, sleep on my side, on the couch.
