I'm suffering from sharp pain under the right rib cage,constant nausea especially after i eat,sometimes i wake up nauseous, when i burp i feel like i'm going to throw up, indigestion,constipation and heartburn and abdominal cramps?

Doctor can examine: Many things are in the upper abdomen: stomach, pancreas, liver, small intestine, bile ducts, large intestine, abdominal muscles, etc... Exam by a primary care doctor can help figure things out, if symptoms are more than just mild. Pain in the right upper abdomen, especially symptoms after eating, can be due to problems in the stomach, liver, bile ducts, gall bladder, pancreas, etc...
