Do i have herpes ? or am i just being paranoid?

okay 2 days ago i had sex with a friend and it was my first time and i gave him head. then a few min hours later like 3 or 4 i started getting like a copper feeling in my mouth (like a penny) and then i started feeling a weird scrunchy feeling on the edges of my lips like a cold sore ive been putting neosporin on my lips and brushing and rinsing my mouth like crazy to get rid of bacteria....there are no visible signs i can just feel it on my lips... to me it just feels like chopped lips but its just on the edges.... anything holistic i can do?
