It's unfortunate that you received such substandard care
I'd make a complaint to the clinic you went to!!
First of all if you went in with obvious lesions they should've been cultured right then and there and you should've been started on treatment immediately to help speed healing. This NP is not following the 2006 cdc std guidelines for herpes ( no idea if you are in the US or not ).
Don't bother with the igm blood test - it's a waste of time and money. This link is to a post dr hunter handsfield made on it - he's a respected std specialist - http://racoon.com/dcforum/support/20242.html

If he's only hsv1+ or completely negative - then go ahead and get yourself a type specific herpes igg blood test now to get a baseline result. It could be that this is just your first obvious recurrence of a prior infection or it could be hsv1 genitally. As I said the NP did you a disservice by not culturing and typing you
