I was having pain on my right side under the rib cage,recently change my eating and have lost 25 pounds. They decided to ultrasound my Gail Bladder,it was good but they saw a hyperechoic cortical nodule measuring 1.0 x 0.9 x 1.1cm. I am a 57 year old female. Last lab I did showed my creatinine level was 109 never ever had a problem with that ever. Are they related? I am scare, what di I do?
