Use RockTape. Consider taping these areas - http://youtu.Be/bg1-vnibcti support prevents muscle strech and pain - orally take nucleotides which are essential to rebuild and repair tissues. These areas if tender there is inflammation either due to gall bladder or liver sludge consider doing a liver, gall bladder cleanse if no relief check with your doctor to make sure there are no gall stones, infection etc.
Vague. History, duration and severity are very important to any suggestions you might receive. I would consider seeing a dr. To rule out doubts and provide options.
