Shoulder blade pain can have many different causes. Although you may assume you sustained an injury or simply slept in the wrong way, the pain might actually be related to your heart, lungs, spine, abdomen, or pelvis. In cases like these, the pain may be referred, meaning that a problem in one part of the body excites nerves that trigger pain in another part of the body, such as your shoulder blade.
The neck and shoulders are complex and interconnected areas, and medical problems that affect one often affect the other, as well.
