Have ckd stage 3-had uti 1 mth ago went fine, now bad hip and low back pain goes up to the neck no swelling or fever, could be related to my kidneys?

Too complicated . .: Your symptoms may or may not be related.However,since you have CKD at the age of 48 yrs, I would anticipate that you have other medical problems as well. Unfortunately, this is really not the correct forum to try to tease out the cause of your symptoms-I would expect that you already have a Nephrologist as well as an internist/family doctor. PLEASE contact them for further evaluation. Best of luck
