HIV :: Body Ache, Night Sweats, Hot Flashes Throughout The Body

I am 31 years old and had a vaginal sex with a girl of unknown HIV status using two condoms at a time. It was my first sexual encounter. I ejaculated twice and both times I used double condoms as I changed after first ejaculation. Both times the condoms seemed to be intact and I could see my semen inside the condom. It's almost over 28 days now and since the past couple of days I have developed almost all symptoms like pain in the back (I have a history of L3 compression and pelvic hairline fracture in 2007), cough with something in throat, body ache, night sweats, hot flashes throughout the body, had stiffness and pain in the back of neck, not visible swollen lymph nodes , had two time kind of diarrhea today.

Since the day after this exposure I was panic stricken with stress and anxiety and cannot sleep at all with insomnia like features and wake up at 2 or 3 or 4 am in the morning due to all sorts of weird thoughts.
