Actually it is ironic that you mention the kidneys because I have some renal calc and renal failure in one of my kidneys but this pain in my back is higher up. They did a bunch of lab tests last week because they were thinking that I might have pancreatitis again but that was negative. I go to my PC today and hope we can find some answers. The pain in my upper left abdomen is above and to the left of where the band port is. You even touch me there and I scream. I am thinking that i am going to have this thing taken out and think about a revision
