Upon 2 urologists exams i've been told i'm healthy, but i feel a sort of fluid-like mass in my scrotum, typically right side. normal? what is that?

Possible hydrocele: This is a fluid collection in the inguinal pathway. You may be feeling more than your doctor feels. If it is bothering you that much, ask for an ultrasound of the scrotum.

Probably a hydrocele: This is a collection of fluid around the testicle. Is likely relatively small if 2 urologists have tried to reassure you. A urologist will no doubt correct it if you tell him/her that you are finding it tiresome. Otherwise don't worry.
