If you have any suspicious symptoms, you should see your doc. No one here can tell you if its herpes or not, and the symptoms can be from a fungal infection, herpes, dermatitis, an allergic reaction, friction, etc. That's why its so important that you let a doc see it and culture it within 24-48 hours of getting the sore, if possible.
