Hi, I am a 56 year old female, have been acing extreme pain right side, laying, sitting, driving. I can only sit for about 3 hours. I have had previous kidney issues, but have recently had an ultra sound, and a renal LASIK scan. The kidney function I at 44%, however the urologist is happy with that, and fela this is not where the pin is coming from. When I sit it feels like a have a foot in my back, and by my side rib area is very tender, as well as pin in the stomach area, between the naval and the ribs. I have had my gall bladder out. Any ideas what it may be.
