I was put on Vieira Pak and Ribavirin for Chronic Hepatitis stage on August 1 and had to be taken off Aug 25 because my Dr. Never told me to decrease my regular medications and I have been getting sicker and sicker and my eye sight deteriorated I have sores all over my stool is always bright yellow, I have chronic pain, I now have thrush in mouth and and throat. Is the thrush white spots in throat contagious?
