hey nana, it would be very helpful if you can give us more info on your hep c. all your bloodwork, biopsy, etc.
hep c, ra, and cryo can all be related. ra and cryo can be extrahepatic manifestations( hep c symptoms outside the liver). but that is for your dr to conclude.
connies advice is mine as well. see a liver doc. treating the hep c sucessfully, may resolve the ra and cryo. this is interesting, let us know how things go.
