About 3 months ago I had protected sex with a girl I did not know. I know dumb! 2 days later I began experiencing soreness that felt like it was inside the head of my penis. It progressed to my scrotum and then burning sensation and redness on my anus. During the second week I had about a half a day with nausea and an unsteady feeling. The burning/ pain feeling lasted a little over 4 weeks and gradually subsided. Never any sores. At 2 weeks out I tested for everything with the acception of HIV as I was told there is nearly 0 chance of this with protected sex. Everything came back negative but I am sure that was too soon for Herpes. As a precaution I took antibiotics in week 2 that an online pharmacy prescribed to cover all treatable STD's.
1 month without any additional symptoms and all of a sudden everything began to return. This time not as strong as the first but now on week 6 of this episode and symptoms are still there. Additionally, I've begun experiencing tingling in my feet, hands, inner thighs, face, and lower back. This is mild but definitely there. I did have gastric bypass 18 months ago so it is possible that the tingling could be a result of a vitamin deficiency or potentially the anxiety all of this has caused.
I never had any sores throughout any of this. Is this herpes or something else?
