There’s a condition known as ‘porfiria cutanea tarda’ (PCT) that is heavily associated with HCV. It involves iron storage
issues, and can be resolved rather readily by a process known as phlebotomy, or bloodletting. It presents as blisters on areas of skin that are exposed to sunlight; often arms, hands, face, chest, etc. It might be a good idea to avoid direct sunlight until this can be either ruled out or dealt with somehow; I think covering up won’t hurt, and might help a whole bunch.
