I recently had protected vaginal intercourse with a guy of unknown STD status. 4 days later, I noticed a couple of blisters a few inches above my ankle. I don't have any symptoms near my genitals nor am I experiencing any symptoms of an initial outbreak. I guess I'm wondering if the blisters associated with genital herpes can be present on areas other than the genitals. I'm concerned because I can't think of a reason for the blisters to appear where they did. Thanks for any help/advice.
