Continue workup: I trust the workup is going on with you alcohol-free, and perhaps you should stop taking all that iboprofen as this is a famous cause of what you're describing.

Jaundice in adults is not as dangerous in that the bilirubin (which causes the jaundice) is not damaging, but it can indicate a condition that is (liver failure.) in babies, a high level of bilirubin can lead to a condition where the bilirubin gets into the brain and causes permanent damage to the developing brain cells. ...Read more

What causes the bilirubin to build up?

Three mechanisms: High bilirubin that is almost all unconjugated means hemolysis (tearing up red cells too fast) or gilbert's non-disease.

Several percent of humankind of gilbert's non-disease with somewhat higher bilirubins; treating this will simply make you sick. Talk with your physician about any concerns. ...Read more
