Unfortunately the itching is a liver syptom....consult your gi / hepatologist - they wii be more help here than a dermatologist - and don't leave anyhting out -
If you are yellow, you probably are at least stage 3 or 4 and when your alts go up
the itching starts in earnest, prescription meds are good, I.E. vistaril or atarax ask your doc.
You mentioned you're going to see a GI, but you didn't mention a dermatologist. I think a dermatologist is best to diagnose your skin problem and probably will prescribe something for the itching. Many people with Hep C have itching. It's one of the side effects.
Talk to your GI about treatment for Hep C. Also, if your insurance permits, see a Hepatologist. He will be a more in-depth doctor for the liver and can best guide you to your next step in getting cured. Good luck...

Re word your question. You will probably get a bunch more feed back start with something like. Have hcv and now hives, help! then add the rest of your message. I thought you were wanting a listening ear. I have never had this type of reaction. Good luck I know someone on the site will have an answer. PRAX is a good lotion that has pain killing abilities available over the counter.
