left flank pain,blood in urine and UTI'S

hello , im 33 y/o female , ive been having alot of UTI's in the last 10 yrs  the first one was really bad i was urinating pure blood . after that i have been getting uti's  with blood in urine but not visable to the eye . for the last cpl of yrs now i have been having pain in my left flank area ,side , and front up under the ribs . most of the time it feels like a pressure feeling but what i did notice is when i get uti's it gets worse ! i am now trying to get over another  UTI  , i had blood in urine , and bad flank pain . doc sent  me to get a cat scan , im just waiting on the results . my question is could this be a sign of a kidney problem ? i have taken NSAIDS ( naproxen 500 mg  ) in the past  but not consistantly  but freqintly  , doc thought i had inflammation of the ribs . but apparently that isnt the case . Anyways im just wondering if this could possilby be a kidney problem of some sort ? Thank you all for responding and for your input !
