After taking antibiotics for epididymitis the swelling went but pain remained. Why?

Hello doctor,

I had epididymitis twice two years ago. I was given antibiotics both the times. The swelling went but the testicle (epididymis pain) remained. I was given more antibiotics over the next few months to no effect. I went to a urologist 12 months later and was diagnosed with prostatitis upon examination. I was offered prostate massage but said no due to a worry over the potential negative effects of the procedure. Urine and blood test came back negative for STI and bacteria. The only issue was low testosterone. I had to see a hormone doctor for the second testosterone test. He noticed some atrophy of the testicles, for which I had an ultrasound. I was then told that the testicles are of normal size and there is no sign of damage, infection, etc. Since then, the pain has worsened. The epididymis hurts when touched, and spermatic cord feels hardened. There is pain during and after urination, although there is no swelling in the scrotum or groin. I have not had most of the prostatitis symptoms for months like the frequent urination, burning scrotum, anus, etc. The pain is in the back flank mostly in the epididymis and thigh region. Could it be intermittent torsion?What antibiotics would you prescribe? If antibiotics fail, would a spermatic cord block be the way to go? Could I have infected my epididymis from my prostate through over masturbation (two times daily) and made the pain worse?
