Dear Dr,
I am having wormlike irritation in my scrotum. What would be the cause. It comes with mild pain and does not occur frequently. It mainly happens after urination. I have tested for gonorrhea, chlaymidia, HIV, syphillis. They are all negative. Did blood culture; got results today, no growth. But the occassional wormlike irritation has persisted for a year. I have had persistent urethral discharge after urination. But it is gone now. I haven't had the discharge since last week.
