I have hep C and one kidney, stage 2 liver disease, they would not and will not give me the treatment they said it would wipe out my kidney can not get another the hep c will just wipe it out in time. I'm 51 said my liver should hold out for rest of life now only if kidney will, sorry about your friend may-be stopping treatment will help improve health?
i would think from both. wishing your friend the best.
