I wish I'd thought of that when I was going through the staph infection.
I did use ozonated water compresses to stop a shingles outbreak, after it had broken out 3 times in 3 months. And in addition to stopping the blisters from breaking out, it also stopped the pain in the nerve below a rib that was residual from the shingles infection.
That was 2 weeks ago - and the skin went from ready to turn into blisters back to healthy skin, and the pain hasn't come back.
