Doctor's opinion? My neck does not hurt, but I kinda feel some pins & needles in shoulder to the the back of my head what is it?

See orthopedist. Still could be from the neck, shoulder or referred. Common referred sources include: abdomen and heart. Shoulder sources include: arthritis, labral tears, instability, tendinitis, rotator cuff tears, bursitis, painful bony spurs etc. Shoulder blade pain can be from the neck or bursitis around the blade. A herniated disk in the neck could be causing your symptoms. See an orthopedist.
