<s>[INST] I am feeling this pressure on my left side, and it's there almost all the time. I did have a CT done a year ago and the doctor said then my liver was enlarge. Now I'm feeling something there aall the time. Thank's Jonathan [/INST] Hi welcome to the health care magic Liver was enlarged before one year in CT scan.. Hence evaluation needed this time again and you can simply get investigated with USG abdomen According to cause further specific treatment given If liver still enlarged then investigation needed with hbsag detection,  anti HCV detection like further investigation Alcohol history also should be ruled out If USG normal and Liver not enlarged then constipation or any functional dyspepsia can lead pressure in left side Hope your concern solved Take care </s>
