My mother is 43 years old, diabetic, and she had a benign liver cyst a couple of years ago. She had a surgery to remove the cyst, and during surgery her gallbladder was removed and about half of her liver. And now, she has pain on the upper right side of her stomach. With the pain she has heartburn & diarrhea. She is wondering why she has pain, and if the surgery or her disease is related to the pain. Thank you.
