When a patient presents with cervical or shoulder pain, which primary systems should be reviewed?

• A. Cardiovascular, pulmonary, GI systems
• B. Endocrine, immune, lymphatic systems
• C. Genital reproductive, urinary, integumentary systems
• D. Musculoskeletal system only

Answer: (A)

When evaluating neck or shoulder pain, the most important step is to screen non-musculoskeletal systems for conditions that can masquerade as MSK pain or signaling a serious health issue. The cardiovascular, pulmonary, and gastrointestinal systems are prioritized because they are the common non-MSK sources of chest or referred shoulder/neck pain and because problems in these areas can be life-threatening if missed. Cardiovascular screening is essential because chest pain or arm/neck pain can indicate ischemia, myocardial infarction, aortic dissection, or other cardiac events. Red flags to consider include pain that worsens with exertion, comes on suddenly, is crushing or pressure-like, is accompanied by shortness of breath, sweating, faintness, or a known cardiac risk factor history. Early recognition can prompt urgent referral. Pulmonary screening matters since conditions such as pneumothorax, pneumonia, pleurisy, or pulmonary embolism can present with shoulder or neck pain along with breathing difficulty or hypoxia. Look for dyspnea, tachypnea, pleuritic chest pain, cough, or hypoxemia. Gastrointestinal screening is relevant because diaphragmatic or visceral irritation from GI pathology (like biliary disease, peptic ulcers, pancreatitis) can refer pain to the shoulder or neck, and accompanying GI signs (epigastric pain, nausea, vomiting, abdominal tenderness) help distinguish non-MSK sources. Other systems—endocrine, immune/lymphatic, genital-reproductive, urinary—can be involved in certain cases, but they are less likely to be the primary non-MSK sources for typical cervical or shoulder pain during an initial screen. Relying only on a musculoskeletal assessment would miss potential non-MSK and potentially dangerous conditions.
