I,too,wake very early with pain that feels like
someone has attached vice-grips to my spine,between my shoulder blades,then squeezes. It usually radiates to my ribcage,sometimes to my chest. I take ambien regularly (small doses);and hydrocodone and ibuprofen for the ache. But,like most of you,getting up and about for a while seems to make it go away.
I am 60,male. Interestingly,in about 1975,while bending into a grocery cart,I experienced intense,nearly paralyzing pain in that area.
