What Causes Abdomen Pain With Nausea?

Hi Sir, recently I am having some pain in the right lower and upper abdomen with a nausea. I have done my full abdomen USG and Liver function test. The result shows I have a fatty liver with sgpt- 50. Everything else is in normal range. I had suffered from same pain and nausea 3 years ago. But that time I was diagonised by neuro psychological problem and taken Nexito forte and the problem was solved. this time I am very confused about the proper diagnosis, whether this is a same kind of neuro psychological attack or everything is for fatty liver and high sgpt? I am also suffering from a pain in the right upper abdomen for the last 10 years(comes and goes) and tested LFT and USG several times. But this is the 1st time that I have found some abnormalities in the result. Pls suggest. Subhra
