After a long struggle with what was determined to be a virus, a 74-year-old female was admitted to the ER with heart attack-like symptoms. She was, however, diagnosed instead with pericarditis, an inflammation of the fibrous pericardium. Although the pericardium is an internal organ, distinct pain can be felt in cases of inflammation/lesions due to its inner action by somatic afferent fibers via the phrenic nerve. Why would this patient be experiencing referred pain in her shoulder (which is innervated by nerves from the cervical region of the spinal cord)?
