My CKD and I were just discussing if he might have a kidney stone - He had one years ago in Vietnam but none since but he feels as if he needs to go and just said that it's as if the urine is right down ready to come out then nothing.. I do remember when Mom was on PD she would have that feeling. I found it interesting that this post had been viewed hundreds of times with no comments. - any input would be appreciated. He's on HD in center since June 30, 2016 and until now has some output but greatly diminished.
