I felt that I was listened to, but by it being my first time, I think that I need to come back for further evaluation since I had several issues that I needed to have addressed. But the kind of care they provided was good. I just feel that I need to continue so that they can evaluate all the issues that I have going on.

I feel like I should have had results of my urine test by now.
