Testicle Tenderness and pain with nausea

Hello everyone! About 10 days ago I felt a sudden tenderness/pain under my left nut. First of all, I'm a 36 year-old man that has a previous diagnosis of "genital Herpes" back in 1993. I've been on preventative meds in the past like valtrex but over the past 3-4 years I've been taking no meds at all for the herpes.

I'm married & my wife too has contacted genital herpes because at the time of our initial relationship I didn't know of having this sexually transmitted disease due to no real visible symptoms. I was finally diagnosed a while after we were married which wasn't a pleasant time indeed. She too has used Valtrex at times in the past as well.

The pain/tenderness I have/had was mild to moderate but over the past couple days has lessened a bit. I have felt somewhat nauseated at times with some pain going up into my stomach. I don't feel any lumps/swelling down low but I can put pressure & get a mild tenderness/pain still after about 10 days. I've had less energy lately & it's mildly uncomfortable when sitting down but not too bad right now.

Now, I've studied a lot about genital herpes & there's no known possible serious problems after diagnosis. However, this current tenderness/pain has never been there before at any time of an outbreak of genital herpes. I do have usually some tenderness around my upper groin with an outbreak but nothing like that has happened. I know my father has a history of hernias but I've never had any type hernia. This is the first problem of this moderate pain that I've had period of the testicles other than the herpes outbreaks. What might be causing this type tenderness/pain coming from the testicles? My wife & I do have sex regularly & she sometimes gets yeasts infections. She also gets some tenderness in her vagina as well. Could I have contacted an infection from her of some kind? Thanks & help is appreciated.
Oh yeah, I forgot to mention that I am mildly burning when & shortly after urinating as well.
