Most people do not experience much in the way of side effects most commonly reported is mild headache.
I had hep c for 37 years and was diagnosed with cirrhosis after 30 years of infection after failing 3 treatments with interferon based regimes each of 6 months duration.
I was cured 2.5 years ago after treating with Harvoni for 24 weeks along with ribavirin for 15 of those weeks. Only symptom I had was some tiredness from the ribavirin induced anemia.
My suggestion is get treated and get cured that way you don't risk any additional liver damage or the possibility of developing other extrahepatic symptoms from hep c.
Also no longer having to be concerned every time you get a small cut worrying over the small risk of infecting those closest to us.
Personally I believe the risks of continue to carry the hep c virus are far greater than the risk of treating and curing your hep c.
Good luck
