Oh it will work ok again, that is for sure. Kidney stones are painful things, I've had plenty.
Here is an interesting tidbit from healthenlightenment.com:
Calcium deficiency, which is also known as hypocalcemia is directly linked to approximately 150 diseases. Here is a partial list: Acid reflux (Acid Indigestion), Allergies, Arrhythmia, Arthritis, Asthma, Bone spurs, Cancer, Colitis, Eczema, Fibromyalgia, Gall stones, Gout, Headaches, Heart disease, Heart palpitation, Hiatal hernia, Hypertension (high blood pressure), Increased cholesterol levels, Indigestion, Insomnia, Kidney stones, Loss of mental functions, Lower back pain, Muscle cramps, Recessed gums, Rickets.
It might be confusing that kidney stones are included in this list. Kidney stones are a buildup of calcium in the kidneys which are very painful to pass, and surgery is sometimes necessary to remove them. Doctors used to think (and too many of them still do) that the stones formed because of an over-abundance of calcium in the diet and instructed the patients to restrict their calcium intake. This has been shown to be the direct opposite of the truth. Kidney stones are caused by a lack of calcium in the diet. What happens is this: When the body becomes acidic, it leaches calcium out of the bones to neutralize the acid to keep the pH from dropping below the level necessary to support life. But the calcium from the bones is not very bioavailable with only a small percentage being actually used to correct the acid condition, and the rest, left over and inactive, starts to accumulate in the kidneys (and in the joints, and as bone spurs).
Science has proven the stones are not formed from calcium in the diet by using radioactive markers on the dietary calcium. When the stones and spurs were later examined there was not one bit of dietary calcium contained in them. Fully 100% of kidney stones and bone spurs comes from calcium leached out of the bones in order to neutralize the acids in the body fluids. Some doctors still haven't gotten the news and are still telling their patients to restrict calcium intake. That, of course, is going to make the problem worse and cause more stones and spurs to develop, which will lead to the doctors' only response at that point: surgery.
Here is the link for the whole article. Interesting info on how to get the right amount of calcium in the diet, how it is absorbed, etc. Might help.

Good luck.
