From my lumbar problems, I used to drop one shoulder and hunch forward.  Many different types of pain can alter your posture.   
 
I don't think you can put pressure on a disc with any mild or moderate external pressure.   Is it possible that the area that has point tenderness is muscular?  Muscles that are overworked because they are over-recruited due to weakness in other areas, or because they are overcompensating due to posture or pain can have this type of tenderness.
