i m really worried about my mother.her liver enlarged 4cms from normal size.ultrasound reports show that she has fatty liver.but i cant recognize that Is it simple fatty liver disease or critical??? Inspite of this her all liver,kidneys,blood and liver related recommended tests are normal.But she has light pain in her lower right side of ribs.which continuously keep her in restlessness.Doctor says that it is not critical but her pain makes me very worried about her.She has no hepatitis A,B,C.Any one can tell me about this pain or its treatment.if yes then i will be very thankful to him/her.my mother's age is approximately 45 years.
