Recently i have experienced a sharp pain between my shoulder blades. it lasts only a few minutes . it happens when i first get out of bed.

A few possibilities: Pain near the shoulder blades can occur for a number of reasons. Cervical spine degenerative disease can be painful in the morning and after rest, like other types of arthritis, and can be referred to the area described. Same for certain types if tendonitis and bursitis: sharply painful until the "kinks" work out. Any significant pain lasting more than a few weeks should be seen by an ortho doc.
