Hi.for the last 4 days i have a stomach pain and also i can digest even small amounts of food and seemingly lost of appetite.so what's ur opinion?

Go see your doctor: It's impossible to determine what's going on w/stomach pain & lost of appetite despite ability to digest small amounts of food. Maybe it's just a temporary issue. Maybe it's a minor viral infection. Maybe it's just heartburn. Or it could be something worse. Best for you to see your family doc for evaluation, diagnosis & appropriate treatment.
