I have that pain every cycle when i start bloating, it is to the right of the diaphragm, I had a ultrasound done on my liver & gallbladder and both were ok first they said they thought i had fatty liver then they done another test and they said it is ok .Who knows might as well go to the vet do just as good my docs head nurse tells me one thing on the phone about the results then the doc tells me something else.
