So I had protected sex with this girl I met at a bar about 5 months ago. 60 hours later (2.5 days later) I woke up in the morning with intense groin muscle aches/pain and inflammation. I could barely walk. About 1 day after that, my scrotum turned red, swelled up, and my testicles became tender. Not only that, but it honestly felt like something was "swimming" down there and I had this tingling feeling in my scrotum.
I originally thought it was probably HSV-2 (genital herpes), but no open sores or ulcers ever appeared. Within a week or two the swelling died down and my testicles stopped being so tender. The groin pain did die down as well within a few weeks, but even now, five months later, I still can feel a very slight dull ache in my groin if I really concentrate on it. It's not very bothersome or anything, but sometimes when I run around and make too many lateral cuts and jukes while playing sports (and thus use my groin muscles), they start to become quite sore after a while. I guess it's just a reminder that whatever STD I caught still lingers within.
So other than that initial episode I never really had any other major symptoms. Is this just hsv-2 or could I have caught something else like gonorrhea (although I've never had any discharge) or chlamydia?
