My kids don't seem to have these. Every once in a while they will complain of aches and pains but I usually can attribute it to something else, i.e., dance class, karate, or football. My niece, however, had growing pains for several years. She is almost 14 now and they seem to have stopped. She is quite tall though so maybe her body couldn't keep up with the growth of the bones, muscles, ligaments, etc. Although my DS14 is quite tall too at about
5' 10" and he never really had any problems. Hopefully, your daughter will grow out of that eventually. There are some good suggestions here to try and I hope they provide some relief for her. My niece used to use Tylenol and it did seem to help.
