Hi and thanks for the query,
the pain you describe is very classical for peptic ulcer disease
or acute gastrointestinal ulcer disease. Confirmation deserves a complete physical examination and an endoscopic examination to visualize these structures. A test to detect the commonest cause of peptic ulcers called helicobacter pylori
could be prescribed in this case. However other abdominal and non abdominal causes of similar pain syndromes must be considered. A physical examination and its orientations might necessitate the carrying of tests like stool examinations and cultures, an abdominal scan and a chest x ray
depending on the case.
Consulting your primary care
physician or gastroenterologist might be most welcome at this stage.
thanks and best regards,
