....I thought shingles was an outbreak of rash or blisters on the skin that is caused by the same virus that causes chickenpox. Can you please explain the theory (or fact for all I know) of it being caused by a parasitic source?? Thanks in advance for taking the time to answer. I am a new cleanser (almost two years) and have recently started lurking in the parasite forums to research the topic. It's very interesting (and quite disgusting)!
