A. Now which multiple sports are we talking about you have to specify that how much requirement of the child is having for legs for everything because the entire body is on your legs and feet and which I was doing multiple things and a lot of physical sports and legs are used with a lot of energy and all it’s common for them to have knee pain I think your child to number of skills or physical activities in a very early age and it could be associated with deficiency of calcium and vitamin D also so please check with your doctor
