I started my Interferon treatment in Oct 2015 and finished in Nov 2016. I had all the side effects. Now it's Dec 2017 and I have had 2 separated episodes of side effects in the last 3 weeks, high fever, joint aches and fatigue. I was told that I have a virus, but why would I have a virus twice in 3 weeks? I'd like to learn more about the long-term side effects of Interferon.
