Around May 1 after performing oral sex on a girl, maybe 2 days late, I got a killer headache in the back of my head. After a week I started to take penicillin just in case and they eventually went away. I eventually met a new girl , dated her, and had sex with her around May 16 with a condom. Around June 8 I went to my doctor because of a rash around below my pubic mound, not on my penis. She said it could be jock it because I do workout but I never got that before. SHe gave me some ointment and I believe its helping. What worries me is as of today I have a weird tingling sensation at the back bottom of my head around my spine. Could this be herpes? No red dots have appeared on my mouth or genitals, I asked my doctor she said herpes would be apparent after 10 days. it has been almost a month since my last encounter any ideas what the tingling in my spine can be. Do you think its herpes?I am also feeling fatigued the past two days.
