Hi doctor My daughter is 5 year old.. She oftenly complains of leg pain  below the knee  from past 2 years...when I checked with doctor they said it is growing pain. But the pain is regular basis..it starts from evening or early morning.. the pain will be there more than 2 hrs.. Is there any vitamin deficiency or something else. Even her teeth also started falling early... She almost lost 3 of her teeth and 2 teeth had grown up She has lot of cavities in her teeth as well We regularly brush but the cavity does not go away. Is this some kind of vitamins deficiency Please advise Thanks
