I'm going to ramble, too.
Uhhh, yes you can affect calcium balance by taking magnesium, if your body had already begun robbing your bones of minerals to obtain the magnesium it craved. Your body will sacrifice your skeleton to stay alive.
If your body starts obtaining sufficient magnesium from diet/supps, it indirectly influences the parathyroid gland, and induces increases in parathyroid hormone levels. In bone, that hormone stimulates osteoblasts, the cells that are constantly redepositing the bone salt hydroxyapatite. Kidney cells pull more calcium back out of urine, and enhance phosphate excretion. What would mess this up is not having enough calcium also in your diet, and/or not enough vitamin D. Hypomagnesemia causes end-organ resistance to PTH and inhibits the hypocalcemic feedback loop through uncertain mechanisms.
Your symptoms are consistent with hypermagnesemia, so there is something messed in your PTH response.
I think you should discuss this with a doctor, preferably an internist. Your kidneys and your parathyroid aren't communicating properly.
Does your bloodwork ever show disturbances in phosphate?
