Yes, I would recommend the western blot as you suspected. My experience is that once a person fails to have an infection picked up by the ELISA (but is picked up by the western blot), they miss getting it picked up by the ELISA every time they test.
It really doesn’t sound like herpes to me with no lesions. Have you talked with your regular provider much about this tingling and numbness? If not, I think you should, separate from herpes concerns
I am not a fan of the immunoblot, actually. We used to use it in our clinic, but I found it difficult to read in some cases and it did not sort out low positives that might have been false positives. Please arrange to get the blot to help you clarify what is really going on here.
You’ve got two more questions/posts here, so don’t hesitate to ask me if you need clarification on anything.
