Back Pain
The kidneys are basically located at the back of your abdomen. Thus, when the infection causes them to become inflamed, pain receptors would send pain signals to your brain and make you feel back pain. The level of intensity can vary, depending on the duration. In most cases, it might range from dull, sharp to excruciating. You can feel it from the middle to lower part of your back, especially when the infection spreads to your bladder. [4]
