I'm not sure if I'm in the right place? Pain in pubic area.

For the last for days i have had pain or well a ache around the top of my vagina where my pubic hair is down my lips. I don't have any pain inside my vagina, no discharge, no pain when I urinate. I do have herpes but I have no blisters, lesions, bumps or redness. I'm sure it isn't herpes as I have had it for over 10 years and it has never presented like this. Does anyone have any ideas as its very uncomfortable 😬
