Epididymitis refers to the inflammation of the epididymis, characterized by enlargement and pain, caused by infections from pathogens such as bacteria. The main cause of epididymitis is usually a preceding infection such as urethritis, bacterial prostatitis, or vesiculitis that was not timely treated. Bacteria spread along the vas deferens to the epididymis, leading to epididymitis. Additionally, trauma to the epididymis can also cause epididymitis. Another common scenario is related to certain medical procedures, such as prolonged catheterization or after undergoing plasma electrocautery surgery of the prostate, which can easily lead to epididymitis. Once epididymitis occurs, it is crucial to promptly treat it with antibiotics. During treatment, it is advisable to consume a light diet, avoid spicy and stimulating food, rest as much as possible in bed, and keep the scrotum elevated. (Specific medication usage should be conducted under the guidance of a doctor.)
