Article in English: One way to distinguish between back and kidney pain is to think about whether you have done anything recently that is likely to cause back pain. If you have done a lot of heavy lifting or have bent over for a long period of time, your pain is more likely to be back pain than kidney pain.  If you stood or sat for an unusually long time recently that could cause back pain. Also, if you have an existing injury to your back it is likely that new pain is related to that previous injury. Because the kidneys are an integral part of the urinary tract, infections and other problems with the kidneys often show up during urination. Look for blood in your urine and pay attention to increases in pain when you urinate.  Your urine may also be cloudy or dark if the pain is coming from your kidneys. You may also feel an intense need to urinate when you are having kidney problems, such as kidney stones. In some cases of back pain you may experience numbness due to problems with nerve compression and blood flow down into the buttocks and the legs. This is a common symptom for those suffering from back pain related to the sciatic nerve. This numbness can even go all the way down to the toes in extreme cases.
