my boyfriend has dark (brown) urine and the whites of his eyes are yellow. He has been sick for about the last week, his symptoms have included chills, fever off and on, reflux, heartburn, diarrhea for a few days, and he has lost about 15 lb. in the last 2 weeks. He went to the hospital and they ran lab tests and they seem okay, then a cat scan that only showed a few gallstones that were not blocking anything, then a ultrasound to take a better look and they can t figure out what is causing his liver to act up. can you help?
