Epididymitis is inflammation of the coiled tube at the back of the testicle that stores and carries sperm. It's often caused by a bacterial or sexually transmitted infection.


Pain and swelling are common symptoms.


Treatment usually is antibiotics. Sometimes pus may need to be drained or part or all of the coiled tube may be surgically removed.
