Hi welcome to the health care magic For hepatomegaly investigate with USG abdomen, liver enzymes estimation etc.. If no significant liver pathology present than no need for worry regarding that.. If history suspicious than better to investigate with hbsag and Anti HCV serological testing by ELISA.. The burning pain in throat and chest suggest acid reflux For that rabeprazole like antacid prescribed Take small meals and avoid high fatty diet Fried food consumed less and eat fruits and fruit juice more Elevate head while sleeping by putting pillow below head Coffee , chocolate etc avoided Avoid smoking if habit Good food for liver consumed like onion, carrot, neet root, avocados etc Take care Consult physician for examination
