Ive got hepC and have had the same problem of blisters on my feet. Generally quite small blisters but also very itchy and they hurt when they burst. Also dry itchy skin on my ankles. Before I knew that I had hepC, the doc said it was exma and that the only treatment was steroids. I later found out it was a common symptom of the hepC.
Ive been taking Miracle-Mineral-Supplement for 7weeks, since then Ive had no itchy skin or blisters. I have not applied it directly to my skin. I dont know if I will clear the virus completely but feel loads of benefits already, only time will tell.
