Check out your liver and gallbladder.
If the pain happens after eating, decreasing over 12 to 18 hours, intensifying after taking a deep breath, sometimes radiating to back or below the right shoulder blade, can be due to gallbladder disease.
If the pain feels more like abdominal pressure or discomfort over the liver (below the left rib cage), you should be checked for liver infection like hepatitis, or you may have a fatty liver.
Abdominal pain like tenderness over liver can indicate more serious conditions like cirrhosis, tumor or cancer.

Visit your physician for true diagnosis!
