You ask mr. lewin to describe his pain in more detail. which symptom is consistent with peptic ulcer disease?

Burning epigastric pain

If you ask Mr, Lewin to describe his pain, he might describe a symptom which is consistent with peptic ulcer disease which is burning epigastric pain. Often, those who experience this, feel pain in the upper abdomen just below the ribs during or right after eating or if they lie down soon after eating. The ulcer may be a break in the lining of the stomach (a disorder known as the gastric ulcer) or a break in the lining of the first part of the small intestine (known as a duodenal ulcer).
