Typical symptoms of stomach pain include a feeling of pressure or fullness in the upper abdomen, acid regurgitation, heartburn, latent nausea and stabbing pains that often radiate to the left or upwards. Some people also complain of so-called fasting pain or discomfort that occurs directly during or after eating. These symptoms can vary in severity depending on the cause. It is particularly important to localize the symptoms correctly – because it is not always the stomach that is actually behind the symptoms. A differentiated assessment can help to initiate the appropriate treatment.
