Another common warning sign of kidney stones is nausea and vomiting. This is normally due to the shared nerve connections that exist between the kidneys and the GI tract, which can then set off the feeling of an upset stomach, which causes the feeling of nausea, leading to vomiting. There are also times when these symptoms are due to the intense pain that occurs from having a kidney stone and infection. Again, this is yet another sign that should not be ignored and requires medical attention.
