Is it possible to have such severe reaction to hsv without ever having an outbreak? All prodrome no outbreak?
It is possible but not likely
Would it be worth jt to get tested for hsv at this point or just visit my primary care for the nerve pain?
Yes, I think now it is appropriate to do an IgG test (blot is better but you could start with IgG).
Did you have a sexual encounter with someone known to have HSV 2?
I did some research on elsberg syndrome ? How likely is this what’s happening here, considering how rare it is ?
I don’t know anything about that, sorry
