LFTS: Your liver enzymes are high, sods like you have a doctor who is following you, I would keep checking with them and possibly see a hepatologist. You may have an infection, you may have a gall bladder problem (yet sounds like ultrasound done already), you may have had low blood flow to your liver suddenly… Many possibilities, keep up with your doctor.
