Dear friend, welcome to HCM!
Pain on left does correlate with enlarged liver.
However he has increased echogenecity of the liver on USG. this indicates a possible chronic liver disease
He needs to be evaluated in detail including a physical examination, blood profile (CBC, urine routine, LFTs, urea, creatinine
, lipid profile
, ECG, Xray chest) and a gastro enterologist opinion.
Please see a good physician first to start the evaluation.
Take care and please keep me informed of your progress.
I hope to have answered your query satisfactorily.
