I Just Spent 2 Days In Hospital Hooked Up To

I just spent 2 days in hospital hooked up to IV and on a stric liquid diet. I went in with severe abdominal pain to the poin of throwing up. They ran blood work, did an EKG rule out the heart. I was released today because my enzyme counts were 50% better and I had symptoms of feeling better. Other than feeling tired. I am still experianceing some discomfort in the abdominal area and don't have much of an appetite. There has been a flu virus going around family members and doctor thought it could my attack could have been caused by that. My pancreas was fine but was told my liver was unhappy. In the passed week or so I've ealso experienced more than normal swelling in ankles and lower legs. I am a little concerned that it is more than a virus that has caused this. Are you able to provide any additional suggestions or input to my concerns?
