USG reports showing no Varicocele but.

I am having pain in my left testicle and lower abdomen region with frequent urination. I go to 2 different doctors and they advised me of getting usg report to rule out hernia hydrocele varicocele etc... I had done 2 usg from different different radiologists... Both the reports are normal. So doctor diagonised me with bacterial infection epididymorrchitis. I have been on antibiotics and other medicines from last 10 days.. my abdomen pain is gone and also my left testicular pain is getting relief BUT i find the swollen veins are there at upward of left testicle as it is... But in usg there is no Varicocele... I even told the radiologist to scan my varicocele in standing position still he didn't find anything. Now I am in tension by thinking what it is...I just want to know that does bacterial infection do cause veins to swollen? and also my left testicle is upwards than my right one...as I am not diagonosed with varicocele but upon checking my scrotum I feel sad and anxiety.
