If your child shows signs like bone pain, delayed growth, muscle weakness, or skeletal issues, it’s time to visit a doctor. The doctor will do a physical exam and ask about your child’s medical and family history, diet, and any medications they’ve taken. They might also run blood tests to confirm rickets and possibly a bone density scan to check calcium levels in the bones. Adults with similar symptoms, like bone pain or muscle weakness, should also see a doctor to figure out what’s going on.
