From what i understand about any of the herpes zoster viruses, there is a distinct tingle and or burning or pain or otherwise unmistakable sensation that precedes the breakout. Sounds like a reaction to something. Allergic dermatitis should clear before a case of herpes...that should answer it. Or a walk in clinic, Dr.can tell or do bloodwork. Goodluck!
Im pretty sure that sounds like herpes unless you are allergic to something
