OK, the nurse practioners (whom I like better than the drs) said the pain was from the chemo slightly enlarging the liver. This interfered with the diaphram on a deep breath, hiccup, etc.
They said that this could be a cause of concern, but because none of the other liver problems seemed present, jaundice, difficulty urinating, etc, we should just treat the pain.
Lortab is now my friend.
Thanks
