It is recommended to go to the hospital for examination to clarify the specific cause and then deal with the symptoms. This condition is often seen in testicular inflammation, epididymitis or spermatorrhea. When inflammation occurs in these areas, swelling of the testicles or epididymis can occur, and when the inflammation spreads to the vas deferens, inflammation of the vas deferens can occur and manifest as thickening of the vas deferens. When the vas deferens is touched by hand, a stiff vas deferens can be felt, resembling a tendon, and is associated with pain. The epididymis is connected to the testis downward, and sometimes the boundary between the enlarged and thickened epididymis and the testis is not clear, so it is mistaken for the enlarged testis more obviously, at this time, ultrasound examination of the seminal vesicles is needed to clarify. After the diagnosis of inflammation, anti-infection treatment should be given, and the drug can be cefuroxime sodium 1.5 grams for injection, intravenously, twice a day, and moderate rest is needed to avoid excessive walking, which may cause the testicles to swing in a pendulum-like manner and worsen the pain.
