Burning Epigastric Pain

Gary is a 48-year-old male presenting with several weeks of burning epigastric pain, relieved by food, with recent dark stools. I'm a 48-year-old man with a few weeks of a gnawing, burning pain in the upper-middle part of my belly. It tends to come on when my stomach is empty or at night, and eating sometimes makes it better. I take ibuprofen most days for chronic knee pain. Your task is to take a focused history from this patient.
