5. Pain in the Side
Your kidneys are situated in the upper part of the abdominal region near the back muscles, on each side of your body. So, if you are experiencing pain in these general areas on either side of your body then it may be associated with the kidneys, and in that case, it could be a sign that you are developing a kidney infection.
However, as with many of the other symptoms in this list, it can be easy to dismiss as a symptom of something else. In this case, you could easily dismiss it as regular back pain that occurs from time to time due to other stresses or injuries.
With kidney pain in particular though, it will usually feel as if it is deeper within the body, and may also occur at a higher point in the back such as the lower part of the ribs. If the pain is lower, it could still be an infection – see below.
