Get Rid Of Shoulder Pain And Muscle Strain. Pain between your shoulder blades (or scapulae) or between your shoulder blades and your neck can be caused by a variety of factors. These pains are frequently fleeting and are caused by nothing more than weary muscles or minor strains that will recover rapidly. If you’re aware of this, your discomfort or pain shouldn’t be a cause for alarm. However, there are some types of pain that are caused by illnesses that demand immediate attention. Referred pains are pains that occur as a result of a condition or injury to a body component that appears to have nothing to do with the back.
