Hepatitis B

I have been diagnosed with Hepatitis B but don't feel any pain or complications. Almost 8 years ago first time i was diagnosed with Hept B, but after medical test reports from Agha Khan, Doctor recommended not to use any medication, as I was 18 years and mature, my immune system will take care of it. But recently in medical checkup I have still HBsAg Positive and reactive (reports attached). Do i need proper treatment? and is it curable completely?
