Doctor can evaluate: The liver and gall bladder are there, along with some other things such as parts of the small intestine, diaphragm, and pancreas. A doctor can check to see if the liver, gall bladder, and pancreas are healthy or not.

Too little informati: It is important to know more about the circumstances under which you began to experience the pain, such as any trauma, did it occur after stretching unexpectedly (like a muscle strain), or after coughing vigorously (you can strain the muscles between the ribs, or even break a rib with severe coughing.) are you a smoker? Get a chest xray for malignancy or infection.

A variety of choices: You will need to see your physician. In that location we can think of a variety of things in the that location - most commonly it could be a gall stone, or a kidney stone or something in the lungs there can other anatomic structures there - so you need an evaluation.
