I was told i have gallstones when i had my kidney stone during a ultra sound by the nurse and sometimes i have bad cramps under my breast on my left.?

Gallbladder: Is under your right side, the lower edge of your ribs.Look it up.

Unrelated: Almost 23% of the general population have asymptomatic gallbladder stones. Symptomatic cholelithiasis is associated with pain after eating in the epigastric/ right upper abdominal area in a person with gallstones on ultrasound. Your symptoms most likely are not related. I suggest you have it checked by your pcp. Good luck.
