and HIV would make the rest of your lymph nodes bigger in your body and not just one area
Many people have slightly swollen lymph nodes for unknown reasons. If they are tender or are increasing in size, this is somewhat more suggestive of some sort of active problem. It would be most unusual for genital herpes to cause several continuous months of swollen inquinal lymph nodes, particularly if you took Valtrex over a thee week period.
Foul smelling urine is not consistent with herpes infection.
