anayortiz 16 Posted March 12, 2013 I've been having a lot pain on my lower back side of my flank (right upper hip area) and it's a horrible feeling. I'm calling my doctor this morning, i remember them saying i had a cyst in my kidney so that's probably what i have that's causing that massive pain :-( I did some research on WebMD and most of the symptoms are exactly either a kidney infection or UTI, I haven't been sleeping that well either I've been tossing left for about a week now and the pain it's horrible.
