I have been sleeping inclined for about a year now. I experience tightness and pain of my upper back and neck muscles. This has persisted despite the multitude of ways I've tried adding pillows to support different parts of my body. All I can think is that my upper back and neck are trying to keep me from sliding down the bed and are tensing up??? This is despite the fact that I put a pillow under my hips for that purpose.
Any help and suggestions would be GREATLY appreciated, because I'd like to continue sleeping this way.
