I have had kidney infection in both kidneys for at least 6 months. I have tried EVERYTHING I can think of - except cranberry - I am allergic to that. But I have been doing blueberry. I have been on multiple rounds of different antibiotics - which worked while I was on them but the infection would always return within two days to a week after I finished the antibiotic. Two nights ago, I had the worst kidney pain yet. I had read on EC about using baking soda for kidney infection but was always afraid to try. But in the wee hours of the morning, I finally gave in and mixed 1/2 tsp. Baking soda in 8 oz. of water. I did not like the taste. The pain did not go away but I went to bed and slept very well. The kidney pain was still there in the morning and I did a dipstick test and sure enough, the infection was pretty bad - the urine looked the worst I have ever seen it, although there were no nitrites.
However, there was something in that urine I had never seen before - a small amount of sediment! I booked an appt. for a urine test at the dr's a few hours later. To my utter amazement, the dr's test came back negative! I still had the pain, but I attribute it to the fact that I am pretty sure I have yeast that affects my kidneys and this was detox. I have had that before when I soak my feet in hydrogen peroxide and water (1 cup H2O2 to a gal. of water).
As I write, it is the next morning and I still have mild but decreasing kidney pain, but the best part is, my urine is clear as can be and I have not seen such a good dipstick test when not on antibiotics, since I started the dipstick tests 6 months ago. I only took one drink of baking soda and water.
