I don't know if I have a kidney infection as I have a lower back pain which I know is not muscular. I check my urine and it is a bit cloudy. The pain seems to also go towards my side in the front. I had a kidney stone in 1972 and had to have surgery. It has been okay since although, I was told that I have a cyst on one kidney. I have been eating a lot of meat as I wanted to loose weight and is following the protein diet since last September. Could this have anything to do with it? Should I see a doctor? I don't run any fever but my body temperature is below around 36 which is 97. I am not necessary sick but feel a bit nauseated. It could be my nerves from not knowing. I have fibromyalgia, asthma, underactive thyroid, hypoglecymic. What do you think is wrong with me?
