Generally speaking, think CHGZGJT for a herpes flare. If there is slight wiry faint tension pattern, I would go for it knowing it will be shaoyin later. If it truly is all faint and no wiry and/or CHGZGJT has been tried and didn’t work, then I would think GZJHQT for the sores. Maybe plus FZ. If the numbness is more of an issue, then HQGZWWT.
