Hello from JustAnswer.
If there is an underlying bump that is visible beneath a scab, it does not sound like how a herpes lesion is usually described. The fact that there is no pain or tingling would make herpes less likely, but does not eliminate the diagnosis as a possibility. The fact that it is going away is not a good sign that it is not herpes, as herpes lesions will resolve spontaneously.
Rather than basing comments upon a description, though, I would be able to make better comments if you could attach a picture of the these areas, preferably a close-up picture or a high resolution image that will allow for zooming in.
Could you attach a picture of the lesion?
