I have been having a sharp sometimes burning feeling in my right shoulder blade. sometimes this pain moves to my shoulder. ?

Cervical radiculitis: Cervical radiculitis due to compression of nerves in the cervical spine can commonly cause pain in between the shoulder blade as well as the shoulder. Referred pain or a primary shoulder etiology is also considered. Disease of the gallbladder (usually cholecystitis) can also cause pain in the right shoulder blade, but less likely in the shoulder itself. Consultation with a physician is advised.
