A 48 year old lady presents with intermittent upper abdominal pain for 6 months. The pain is dull, radiates towards her back and is often precipitated by heavy meals. There is no history of fever or jaundice.
Three months prior to the onset of pain, she had begun to experience vague upper abdominal discomfort, intermittent heartburn and indigestion.
Her medical history is unremarkable. She does not smoke, only consumes alcohol intermittently, and is nulliparous.
