Hi. Thanks for your query. Read and understood your history. Male / 32 - single - testicular Atrophy 1 year back and has Epididymitis on the same side, which is now recovered well but you are now feeling that something is puling your testis (the atrophied one) down in your nerve - meaning lust towards left of penis in the groin if you do not wear underwear. This is not at all normal and may suggest something still there in the left scrotum. There may be still a focus of infection. I would advise you the following in such a situation: Get a clinical evaluation and Physical Examination by an Urologist. Ultrasonography and color Doppler examination of the whole area., Antibiotic cover if there is an evidence of an infection . Scrotal support. Removal of the testis and epididymis if diseased and not amenable to the medical treatment.
