The multiple negative HIV tests would make HIV very unlikely.
Infection needs to be ruled out. Urine tests and a urethral swab can look for gonorrhea and chlamydia. The prostate should be palpated to rule out infection, which can present with the scrotal symptoms.
You can consider a transrectal ultrasound to image the prostate for infection, as well as a prostatic massage to milk out and analyze any prostatic fluid.
Regarding the tingling, I agree with the MRI and EMG. Negative testing would make neurological diseases less likely. The blood tests are negative as well.
With the continued non-revealing testing, many of the major diseases have been ruled out. Obtaining a second neurological and urologic opinion can be considered, preferably at a major academic medical center.
Followup with your personal physician is essential.

I also have pain in left testicle...especially after ejaculation.
I think mostly I'd like to know if I'm a medical abnormality or not...
And I know STDs don't really show these symptoms but the timing was just so convenient...
Sorry to post a million times...my urologist says he thinks the tingling in testicles can be caused by a muscle pull. Is this possible? And even so, would it last 4 months?
I have had Peripheral Neuropathy for 3 years. Symptoms are similar to what you are describing. My feet feel like they are burning, numbness. My fingers and toes are numb.
Not necessarily connected is that my left testicle started getting swollen. Eventually, They performed surgery to reduce the swelling. They drained 700 ml of fluid.
My Neurologist believes the Neuropathy is from Pancreatitis not Diabetes.
I was dx with HepC in 1991, Cirrhosis in 1999.
Gabapenton 400mg twice or more p/day relieves the pain for me.
Ask your Doctor.
I am currently on 300mg on Gaba. Helps a little..but doesn't make me feel all the way better for sure.
