What could cause shoulder blade pain?

Shoulder pain: Pain in the shoulder girdle can be due to impingement syndrome, rotator cuff tendonitis/tear and or bursitis, cartilage damage or muscle strain as well other possibilities. Simple exercises to strengthen the rotator cuff and shoulder blade muscles should be of benefit. If pain persists then consider formal physical therapy or evaluation by your orthopedist.

Multiple Things: Many sources can result in referred pain to the shoulder blade. Along with the neurogenic sources like cervical (c6 for example) and the suprascapular nerve, we also see many patients with occult shoulder pathology have referred pain to this area. Patients who are very flexible can also have occult shoulder instability refer pain to this area. http://www.theshouldercenter.com/shoulder-pain.htm.
