Did you know that many people can get rid of kidney stones by taking the herb Chanca Piedra which dissolves stones gradually until they become tiny and can be urinated out. It takes a while but many people have found relief.
What makes you think that candida has anything to do with your kidney pain? How would they even test for something like that?
Did you have an ultrasound done on your kidney to confirm that you do in fact actually have kidney stones?
Kidney pain can be caused by a variety of causes. UTI infection by bacteria is also a common cause. Have you had your urine tested for microbial growths?
