A swollen, red or warm scrotum, painful urination and enlarged lymph nodes in the groin are symptoms of epididymitis. Discomfort in the lower abdomen and fever are also symptoms, according to Mayo Clinic. Epididymitis becomes chronic when the symptoms last more than six weeks or when they recur.
Inflammation of the epididymis, a tube located in the rear of the testicles, is known as epididymitis. Epididymitis is most common in males ages 19 to 35, according to Healthline. Either a bacterial infection, such as a urinary tract or prostate infection, or a sexually transmitted infection, such as gonorrhea and chlamydia, cause epididymitis.
