Sign: Groin pain
Men might feel the pain of a kidney infection deep in the groin. “When we’re in utero as embryos, our kidneys start lower in our body, and as the fetus grows, the kidneys ascend,” says Dr. Modlin. “They have that same nerve supply as some of the structures down in the groin.” You might think your testicles are the problem, for example, but if you have other UTI symptoms, your doctor will test for a kidney infection.
