Right testis small in size. Suggestion.

Hi sir, This is Anuj Burewar My right testis is very small in size from last 10 days (may be more than this but i have checked it 10 days back only). As recommended by the practo doctors i went for ultrasound sound of the whole scrotum. Please go through the attachment for the ultrasound report of scrotum and kindly check medical record for previous medical history I have no pain while passing urine or any other. Please check the report attached.                                                   Previous Medical  history-                                    Diagnosed with epididymo orchitis (right testis side) on aug-2016, admited in hospital for a week given some antibiotics and got cured. After 2 months(oct-2016)  i was diagnosed with Ankylosing spondilytis after that taking some NSAIDS it was back to normal and following physiotherapy and yoga it is in  control from last 2 years. Please provide the suggestion..
