Just started having back pain just below shoulder blades mostly middle of back. it sometimes makes breathing harder. saw doc 5 days ago for possible ear infection- all was good/blood work spot on. i slept in chair past 2 days. should i be concerned?

See below: In most cases, upper back pain caused by: muscle strain or injury to the muscles, ligaments, or discs. On the other hand, there are less common, but potentially more severe and rarely, life-threatening, conditions that should be ruled out especially if associated with shortness of breath, nausea, dizziness, sweating, anxiety: aortic dissection, pneumonia, pulmonary embolism. Re-contact MD or ER.

See general surgeon: Your ear infection has nothing to do with your back pain. It could be pancreatitis, kidney stone and other causes!
