Good morning to all. I need your input. Have you ever had a bile duct issue that did not show up on diagnostics testing? If so, how was it finally diagnosed? My ALT and GGT are extremely high. My bilirubin is normal as are the other two liver enzymes. I have had an ultrasound and an MRI-MRCP but no issues were found. I am three months post liver transplant. I have so many issues that direct to trouble with my biliary system. Chronic itching, nausea which sometimes leads to throwing up of bile, shortness of breath, and my tremors have become more intense. Your input would be greatly appreciate! Thanks!!!
