Can Diastasis Recti cause bladder and testicular pain in people that work out daily?

It is very unlikely that diastasis of the rectus muscles should cause pain in the bladder and testicles.  In fact, one would be more likely to feel pressure on the bladder from an overzealous repair of diastasis than from the presence of diastasis.  while it is good news that the urologist has found no significant problem, a visit to your internist would likely be the next best step for a full workup.  Best wishes.

Thanks for your question.  Sorry to hear that you are so uncomfortable.  I would agree with my colleague that your symptoms are unlikely to be attributed to the diastasis.  Unfortunately, those symptoms are very non specific.  I would encourage you to start by visiting with your internist for a history and physical exam.  You likely will require some imaging and possibly lab tests to sort this out.  Best of luck.

Thank you for the question.
Diastasis recti is simply separation of the rectus muscles from there normal attachment in the middle by stretching.  Its is not to be confused with a hernia.  I have to wonder how you were diagnosed with diastasis recti and how this was properly distinguished from a hernia.
Diastasis recti is usually asymptomatic and I have never seen a case associated with bladder or testicular pain.  On the other hand -- these symptoms may be associated with inguinal hernias.  
I would recommend seeking consultation with a General Surgeon to determine the source of your pain.  Your urologist is quite capable of diagnosing an inguinal hernia.
I hope this helps.
