Your SGPT levels are almost three times the upper limit of normal, this suggests reactivation of the disease. I would advise you to Get a HBV DNA viral load
done and in case it is detectable you would need to start treatment. It would have to be a medicine other than lamivudine
as now better drugs are available.
I would also suggest you get a USG and complete LFT done.
I would advise you to consult a gastroenterologist
who would guide you regarding the further management plan
Hope this helps
Do get back in case you have further queries
