The western blot is the next step.
First of all, the IgM should never have been done – the CDC recommended that and so do I, given the high rate of false positives (not your issue though).
Your HSV 1 is a low positive and it may or may not be accurate
The spot you describe sounds nothing at all like a herpes lesion.
Even if you are truly positive, we cannot know where the location is – oral or genital. have you ever had a cold sore on your lip or in your nose?
I think you’ve been getting a lot of poor herpes information!
If you want to know for sure about your herpes status, yes, the blot is your answer.
