Kidney disorders can begin with no symptoms. Sometimes we might notice symptoms but assume it is a common illness or just normal aches and pains. It never occurred to me that a lower backache can be a symptom of kidney stones or kidney infection until I ended up in the hospital.
Before I was diagnosed with kidney disease. My symptoms was chest pain. After I was sent to have a CT. I was told that the mass was so large, that it was the reason, I was having chest pain. So my left kidney was removed.
