What Causes Pain And Tenderness Around Ribcage?

I have had some pain in my liver area for about 3 days. Mostly tenderness in my rib cage. It comes and goes. I had my gallbladder out 3 years ago. I ve had this pain before and did a liver cleanse and went to the dr. and blood tests came back normal for liver. It has flared up maybe only twice before and it was after several days of high fat and sugar diet. Could it be fatty liver? I m assuming not cancer since it goes away and tests have been normal.
