I also have Hep C. I too have the cold, numb foot thing. Been through Interferon treatment twice. Neither worked, nor has my Dr mentioned any reason for the foot problems in connection with my disease. I'm still not sure.

Have you been diagnosed with HEPC? Is this a side effect of treatment?
I'm sorry - if this is just about your feet --- I really can't help you except to say that when I was pregnant my feet would get soooooo hot that I couldn't handle it. And even if it is really cold, I still have to stick my feet out from under the covers.
I don't know about numb feet.
