Alright buckle up for this one. I've seen 5 doctors.
25 year old male
In September I felt pain when urinating and tenderness in my testicles after fully protected sex with a new partner. I swab tested negative for chlamydia and gonnohrea, but was treated with antibiotics for 10 days (norfloxacin I think?) and my partner treated simultaneously. Afterwards we were tested negative and went back to having sex, with the occasional unprotected.
My symptoms returned in the form of tenderness in the testicles and the odd flare up of dull pain. I saw another doctor, got another negative urine test but regardless was treated with a 10 day antibiotic variation. The pain subsided, but ultimately didn't disappear.
I also have had an ultrasound which came back clear for testicular cancer.
February I'm feeling pain again. This is all with the same partner who we have not had sex with anyone else. I trust her on this point. Blood tests come back clear.
Girlfriend tests positive for chlamydia again, suggesting that we somehow did not clear it the first time. I take another urine test that again comes back negative. Regardless, I'm right now on day 15 of a 21 day doxycycline regiment with some months away appointment with a urologist. Oh and I still feel (less admittedly) pain in my teticles in the epidydimis region.
How could I have tested negative all of those times?
Why can't I get this pain to go away?
What else could it possibly be?
