It's possible, but I'd get a doctor to look at it anyway. If it's something else, it should be diagnosed and treated. If it's herpes, you might need to use an antiviral cream or other healing ointment to help the healing. It's a difficult area to heal sores because the skin is constantly being stretched and pushed around. I've had an OB around the anus and it felt like hemmoroids with swelling, but one thing about herpes is that it can look and feel different on each person.
