J.P.
We use a good CalMag and the pain is gone within 2-12 hours. The bones need more calcium to allow the bones to grow to their potential. We now do the CalMag with all of our kids every other night and they sleep awesome and never have any pain.
Our friend took her son to 14 doctors and finally, at her wit's end, he took him to a chiropractor by a referral from a friend and she told her to go get calcium/magnesium (NOT calcium carbonate) and his pain was GONE. He'd been in pain for almost 5 years straight.
This will not show up on labs because the calcium gets leeched from the bone and has enough in the blood, so they are checking BLOOD levels, NOT body levels.
