I finished 11 months of interferon and ribavirin treatments for hepatitis C in 2008. 13 years later, I am experiencing many of the side effects that I had when I was taking my shots. I wake up with flu like symptoms, chills, headache, fatigue, and brain fog just to name a few symptoms. I discovered the Mayo Clinic has written about post interferon syndrome. Does any one have any additional information. Are there any treatments
