... can't go sometimes . My urine is really dark the next time it will look normal . What is going on .the Dr said I don't have kindey infection. I am really scared . My back hurts a lot in a area where a nurse told me was my kidney . The Dr said I was not informed right .I feel like drs are afraid of lupus . But kidneys are effected by lupus . What would cause our urine to smell like amonia
