Sobriquet, I had my vit D tested a year ago, and I was defficient... my doc put me on 50,000 IU of D3 2x a week for a month or so, and the vit D levels went back to normal.
HOWever... I never ever had ANY bone pain until the moment I was taking the megadoses of D3. Oh, wow, my bones were aching so badly. After I stopped the megadosing, my bones felt ok, but every other month or week, they flare up again.
I want to blame that month of high Vit. D intake as the instigator of my bone pain.
