Why do some ethnic group acquire growing throbbing? At what age should it stop?
Well, growing pain usually starts when you start puberty, and it stops depending on the human being, but most of the time it will all be over by when you are roughly speaking 16 or 17. Some people failure puberty when they are even 18. There is deffinately no age when EVERYONE stops growing so just be long-suffering and it will probably stop soon!
I used to think that growing pains be just an ancient saying. I took my son to the bone specialist, as his legs and foot were hurting so much. The Dr. showed me his Xrays, and they showed that parts of his foot and leg bones had become solid, while other parts have not YET become solid. That is why it hurt him to walk, and to be surrounded by sports. During this time of bones hardening, as the body grows, it is exalted that the bones are not expected to do things that they are not 'ready' to do, yet. Growing pains last until his bones hardened up, caught up beside his growth.
