Happy to report there is no outbreak. Even if there is, I would still choose soaking sores in fresh urine for 15-20 mins, 2-3 times daily, until sores are painless, dry and healing.
The first thing to notice would be the immense reduction/disappearance of pain, on the blisters or other areas (nerve, muscle etc). Next, would be blisters drying, even tiny ones, and protective skin forming over them. The new skin will continue to grow until it falls off by itself, replaced by new, tender skin.
Do try it. There's nothing to lose but much to gain.
