Differential Diagnosis

The patient's symptoms of pain in the right upper quadrant rib area, right clavicle, neck, and shoulder, accompanied by burping and sharp pain upon breathing, suggest several possible diagnoses. These can be categorized as follows:

• Single Most Likely Diagnosis

  • Gastroesophageal Reflux Disease (GERD): The symptoms of burping and pain in the upper abdomen and chest area, especially after eating, are classic for GERD. The pain can radiate to the shoulder and neck due to the referral of visceral innervation.

• Other Likely Diagnoses

  • Peptic Ulcer Disease: The pain in the right upper quadrant could be indicative of a peptic ulcer, especially if the patient has a history of NSAID use or Helicobacter pylori infection. The pain can radiate to the back and worsen with deep breathing.
  • Cholecystitis or Biliary Colic: Although the pain is typically more localized to the right upper quadrant, it can radiate to the right shoulder due to the phrenic nerve's innervation. The onset after eating, especially fatty foods, is consistent with biliary colic.
  • Musculoskeletal Pain: The pain in the shoulder, neck, and chest could be musculoskeletal in nature, possibly exacerbated by eating if the patient has a habit of eating in a position that strains these areas.

• Do Not Miss Diagnoses

  • Myocardial Infarction: Although less likely given the context of eating and the nature of the pain, myocardial infarction can present atypically, especially in women, with pain referred to the neck, shoulder, and arm. It is crucial to consider this diagnosis due to its high mortality if missed.
  • Pulmonary Embolism: The sharp pain with deep breathing (pleuritic chest pain) could suggest a pulmonary embolism, which is a medical emergency. The pain's location and radiation, along with the patient's symptoms, make this a critical diagnosis not to miss.
  • Esophageal Rupture or Perforation: This is a rare but life-threatening condition that could present with severe chest pain, especially after forceful vomiting or eating. The pain can be exacerbated by breathing and movement.

• Rare Diagnoses

  • Pancreatitis: While the pain is typically more central and radiates to the back, pancreatitis could be considered if the patient has a history of gallstones or alcohol abuse. The pain usually worsens after eating, especially fatty foods.
  • Pneumonia or Pleurisy: Infection or inflammation of the lung or pleura could cause sharp pain with breathing and might be referred to the shoulder or chest area. However, these conditions usually present with additional symptoms like fever, cough, or shortness of breath.
