glad i can help. whatever you do, do NOT stretch those mid back muscles with stretches that involve rounding your back. the muscles back there are already over stretched. they need to be STRENGTHENED with exercises that pinch the shoulder blades together. any stretches that involve EXTENSION of the torso and limbs will be good for you.. (ie stretches that put you in the opposite position you are in when you work---doorway stretches are especially good)
Wow thanks ofr the information. This hits the nail on the head being that I am a computer instructor. I spend tons of time in front of my workstation. I guess I will work on those back muscles. your awesome.
MUSCLE issue it sounds like. the rhomboids and posterior scapular stabilizers get weak and stretched especially in people who spend alot of time on the computer--it comes from hunching. look up upper crossed syndrome on the net and work on strengthening those back muscles and stretchng the scalenes, pecs, scms, upper traps.
