Results Of Gastro CAT Scan W Contrast (iodine Inject, Barium

Results of gastro CAT scan w contrast (iodine inject, barium ingest) only showed fatty liver (I don't drink and am not preg), "normal" otherwise, but I have increasingly more left side pain from upper abdomen to mid-chest level, in duration and intensity... Need some guidance as to what now? Tests to request? and the "why" to justify, etc. And are "cancer markers" only tested for when there is a confirmed tumor?
