What is a common symptom of epididymitis?

Epididymitis is an inflammation of the epididymis, which is the coiled tube at the back of the testicle that stores and carries sperm. A common symptom of epididymitis includes pain during urination, as the inflammation can irritate the urinary tract. Swelling of the scrotum is another typical symptom, resulting from inflammation and possible fluid accumulation in the area. Fever may also occur due to the bodily response to infection. Therefore, recognizing that all these symptoms can manifest simultaneously makes "all of the above" the most comprehensive and correct answer in this context, as it encompasses the range of symptoms commonly associated with epididymitis.
