Symptoms of Epididymitis The epididymis is a series of small tubes attached to the back of each testicle that collects and stores sperm. One of the most common causes of pain in the scrotum is epididymitis, which is an infection that causes inflammation of these coiled tubes. Epididymo-orchitis is the spread of the infection to the testicle.
Epididymitis is usually a secondary bacterial infection that can be triggered by a range of conditions, such as a urinary tract infection or a sexually transmissible infection (STI). The bacteria in the urethra (the tube carrying urine and sperm from the penis) move through the urinary and reproductive structures to the epididymis. The symptoms of epididymitis include:
feeling of heaviness in the affected testiclesensitivity to touch or pressure in the affected testiclepain in the abdomen or pelvisfrequent urge to urinateburning feeling when urinatingdischarge from the penisenlarged testicleblood in the urinepain when ejaculatingslight feverchills
