How would you know if a back ache is from your kidneys? - back ache treatment more condition_symptoms

I had very bad pain in the package center back on the right side for a few years. I went to the doctor and she told me that I have a kidney infection. I went to a chiropractor and he said it was muscular. Had several treatments with her and no luck. Frankly, I think there is something wrong with my kidneys. While in the hospital during pregnancy, gave me some tests. The nurse told me that "were my level of kidney low, but I have not heard about. What does that mean?" Today I have very bad back pain and nausea. I am afraid it is much more than just a sore back.
