What are the symptoms of this? WebMD says these are:Jaundice (yellowing of the skin and whites of the eyes). Pain in the upper or middle abdomen and back. Unexplained weight loss. Loss of appetite. Fatigue.But its a very vauge definition for all of them(except jaundice).Sure I am fatigued alot, but I stay up late alot and wake up early. Somtimes I'm not hungry, somtimes I am. Yes I always have pains in my upper and middle abdomin, but it could also be gas, so what kind of pain, constant pain, excruciating?
