Hi thanks for asking question. Do you have done your USG of abdomen ?? Do you have high cholesterol and so on gall stone?? Here USG abdomen done to rule out gall stone and hepatomegaly.It might lead obstructive jaundice and so itching is present. If you have taken outside food then it might be hepatitis A as you have sudden presentation. Viral market done to rule out viral hepatitis. If you have habit of alcohol then also liver enzymes elevated but presentation is not such a sudden. If having habit then stop alcohol drinking. Meanwhile take ursodeoxycholic acid and less fatty diet. Cutt of oil in diet for few days. Fruits taken more. 1 teaspoon licorice powder with honey taken daily. Papaiya seed with lemon juice also good herbal remedy. I hope your concern solved. If still need guidance you can provide follow up report and still further guidence can be given... Dr.Parth Goswami
