get on high dose magnesium (build up over 3 days or so to 800mg per day). Mag glycinate. mag makes calcium dissolve and absorb; kidney stones are calcium (ie sign of low mag)
In addition to taking a high quality, highly absorbable magnesium, take Vit D3 and Vit K2 with MK-7. The K2 will keep the calcium out of the soft tissue, ie, heart, arteries, kidneys, directing it to the bones and teeth. It will also help pull calcium deposits out of the soft tissue.
