It depends on what kind of groin pain you are having. Lots of things cause groin pain. Herpes wouldn't be near the top of the list, though.
Some of the "funny feeling" may be from just knowing you have it, and feeling anxious. Some may be that your nerves are irritated, and it will calm down. You could also have a pinched nerve, issues with your sciatic nerve, an anal fissure or any number of things (these have nothing to do with herpes).
What you need, as you know, is an exam. Be sure to describe your groin pain in detail, and let them know that your thighs and legs itch.
Good luck!
