Timely help for Nikita!

My mother and Nikita moved from Pokrovsk to the safer Dnipro. The boy is already thirteen years old, the period when the body is actively growing and changing. Last year, he developed "like a hollow in his chest", his back began to hurt, and it became more and more difficult to do physical education in class. After the examination, the doctors found that the deformation of the chest is happening quite quickly, and an urgent operation is needed.
