I have some tenderness but no visible discoloring or rash around a patch of skin on my right upper thigh. This has been going on for about 5 days. After doing some internet research, I think I might be one of the millions of people who have some form of herpes but do not know it due to very mild, almost symptomless recurrences. I have linked my skin tenderness to a possible herpes infection but I can’t find any hard information on a typical recurrence’s duration.
