post herpatic neuroglea question

four months ago i had genital herpes ,ever since i feel stabbing pain and burning skin sensations.2 questions:1. does the burning sensation must be limited to groin or it can appear around the body to consider to be post herpatic neuroglea? and 2 . the pains and burns fluctuate , one week fine the other very painful or burn is it typical to post herpatic neuroglea?
i did blood tests+ vitamins test and it all was normal.
