Kidney stones are often the reason for pain in your lower back. One in every 20 people develops kidney stones at some point in their life, normally due to a lack of water in the body. The stones press against nerves in the kidneys and cause various degrees of pain. When the pain travels down into the thighs, it is called sciatica. Bioresonance therapy can test to see if you have kidney stones and, if the stones are present, can help remove them. This is done by sending healthy frequencies into your body, allowing the stones to pass out of the body and relieving your pain. Dennis Ludwig, Evergreen Holistic Health Centre, Evergreen@mymts.net
