My aunt who is in her 80 s is in ER now with severe pain in lower left quad--food seems to bring pain on, worse when up. Has done EGD, Colonoscopy, abd US, Cardiac stress test, liver function test, and bloodwork has all been normal (haven t got results of today s bloodwork yet). Had gallbladder removed several yrs ago, checked today to see if there were stones in Common Bile Duct--none. Help please
