Differential Diagnosis

When reviewing the chart you see that this is Patrick Smith, age 42. You met him last month when he brought his mother-in-law in for a sick visit. You remember because you treated him as well for a skin condition.

You enter the room and introduce yourself again to Patrick. He is not the jovial man you met last visit; he appears to be uncomfortable as he reaches forward to shake your outstretched hand.

Patrick says he is in a lot of pain. He thought it would go away but it is lasting and seems to be getting worse. He is also nauseous. He doesn’t think it is anything that he ate and no one at home has had the stomach flu. It is getting worse as he has been sitting in the office. He cannot find a comfortable position to sit.
