JOINTS....is it normal for them to hurt when losing?

My pelvic joints and knees hurts rather badly! Is this normal during weight lost?

I am seven months out and have experienced the same thing scene I was two months out I found and article in one of the weight loss sights that said this is normal especially in the pelvic and knee area because your bones have to adjust to your new weight size.

 Been dealing with the same stuff. Went to a chiro he has been helpful. I had a couple herniate disk and they were hitting my nerve. I have read its just our bodies readjusting.
