Hello, I would like to ask what are the probable causes (and treatment) for stomach pain. My symptoms may be due to excessive alcohol intake 3 nights before. But I am alarmed that it has not passed. The intensity, on a scale of 1-10, is about 5. It drops to a 2 after a meal but runs from 5 to 7 after an hour or so from the food intake. Could it be a bruised stomach lining? or a toxic liver from the alcohol that is causing this? I am 24 years old, female, oriental. Please advise.
