Week 5 Discussion A 50-year-old man has been suffering from substernal pain for the last 5 months, particularly on waking up in the morning. He lost his job a year ago and was suffering from depression. He consumes about 12–16 cans of beer every day. He has lost his appetite too and says that eating aggravates pain.
