Aloe vera juice works wonders for the kidneys. It works on the inside of the body just the way it works on the outside. You can also get aloe vera gel caps.
A shot glass of vinegar every four hours should do the trick. It tastes terrible, but the relief it brings is worth it.
I started taking cranberry 1680 mg...2 softgels three times a day with lots of water. I have also been taking garlic, and enchinacea (which are natural antibiotics) within 6-8 hours after I began the cranberry I could literally feel the infection flushing through my ureters, then through bladder, and out of my body!!! this is like the 2nd kidney infection I have ever had in 32 years. I am not sure which had most effect or if all three combined.. but yesterday I had fever, chills, and to top it off an abscessed tooth...which seems to be getting better too.
Drink cranberry juice,maybe a cup or two, I swear by this, I have really bad kidney pains and I drink some cranberry juice and it goes away instantly
Do not drink too many colas this can cause a kidney infection. If you do get a kidney infection drink nothing but water and it will clear up.
