You want to ask my son, who is fourteen years old, how many years has he been eating chicken breast? Unable to correct; Chicken breast is the sequela of infantile rickets. If it can be found early, it will generally improve or disappear before the age of 5, and 14 cannot be corrected after the age of 4. If it does not affect children's daily life and sports, it can be ignored. If so, you have to go to the hospital for orthopedic surgery.
