Same here. I cannot lay in any position other than my back. My hips are extremely painful -- and everyone knows that a spinal patient cannot lie on the tummy.
And since i've had a few spinal surgeries, laying on the back isn't any too great either. Plus i just found out I have some broken vertebrae too -- so that doesn't make things very pleasant. I "get" to prop myself up with pillows, and "sleep" sitting up!
Such is the life in the day(s) of spinal patients. Right?
