Around several months ago I had brief unprotected sex. Like 2 days after I notice a very small bump on my lip which cause me to immediately stress. The bump later turned to several bumps on the crest of my top lip which are still here. I developed burning sensation on my thighs, lips, buttocks and vaginal area which later all expect the thigh pain went away. Even though I had no lesions at all could this still be a sign of herpes???
