6. Pain in the Lower Back
As mentioned in the previous section which covered pain in one or both sides of the body, which could be a sign of kidney infection that generally causes pain higher up in the back. However, experiencing pain in the lower back can also be a sign that a kidney infection is developing, as well as the possibility that it is simply from a back injury or muscle pain.
Another similar factor of pain in the lower back and pain in the side is that it can be easily overlooked by many people who are used to experiencing this kind of discomfort, but it is nonetheless important to keep an eye on it.
One of the best ways to distinguish between muscular pain and the pain caused by a kidney infection is that the latter will continue no matter what you are doing or what position your body is in. Whether you are sitting, standing, lying down, or whether you are performing strenuous work, the pain from kidney infection will persist.
