Thanks for your query.You are having testicular pain
since weeks.Is it associated with fever ?Most probably it is due to Infection of Testis called Orchitis As regard your doubt about leakage of semen it is not possible for semen to leak without ejaculation.What you think as a semen may be thick secretion of urethral glands.Please consult some Urologist
and get Ultrasound
scanning of abdomen and scrotum done to diagnose the reason for your problems.In the meanwhile take some antibiotics like Tab Ciprofloxacin
500mg twice daily along with and noninflammatory drugs.like Tab Combiflam Twice daily.
