Hi .. I am rahul my right testis is larger than left...I feel a very little pain very rarely.. all that I am afraid is I am going to take exam for ARMY....could you let me know whether it is hydrocele or not?? I have gone through the some questions related to this but I want to know , if I am operated for this can I join in army...I mean is there any possibility of reoccuring the same after it is once operated :$
