Who can tell me what's wrong with this? There were only a few at first, but it's much better now. Is metronidazole gel useful?

You should belong to herpes, a bit like acne on your chest [or folliculitis on your chest]

The main cause of human herpes may be damp-heat gas. When your immunity drops, your immunity can't deal with all the toxins of the hot and humid gas in your body, so this herpes will appear. You belong to the toxin of damp-heat in upper energizer, so you must clear away heat, detoxify and eliminate dampness. At the same time, you must avoid eating [no oil, salt, sauce, vinegar, meat, cigarettes, wine, tea, coffee, monosodium glutamate, chicken essence, etc.]. ].
