I sprayed mine continually with Colloidal Silver. The itching subsided, and they eventually went away.
However a few months later The shingles returned, but in a different area, but the pain wasn't as bad. This is because the virus hides in the nerve centers. This is the reason for all the pain. A person can have the virus eruptions for the rest of their lives according to what I have read. Maintaining a healthy immune system is vital.
Amazon.com has some colloidal Silver gel that might help. Read the reviews. I didn't buy it because I have a CS generator, but the reviews sounded like it might be a good alternative.
