Hello, and thank you, I have had a pain in my left side kind of hard to explain where it is just under my left rib, I have been uriniating allot and one day I had a small amount of blood in my urine, not allot just a little bit on the paper. It is a  sharp pain and sometimes it is really painful. Generally I feel well, I keep active but when the pain comes it is powerful and very painful, I urinate allot at night although i dont drink anything after 8 pm, sometimes my urine is darker yellow and sometimes does not look like it has any colour, sometimes not allow comes out, I am thinking it can be my kidneys?
How old are you?does the pain radiates to your that side thigh?Do you feel any  ChatDoctor.
