I have had pain in my right kidney (flank) consistantly for over 2 months and now it's on both sides. I have had blood work drawn multiple times and it all comes back "normal." I had a ct scan that came back normal. I have been to the chiropractor, done massages, even accupuncture to try and help with the pain. It is not piercing but it is a dull pain that is constant. There have been issues with irregular periods during the same time with pain in the ovaries and they are fine.
