I am Tate Myron, 16 years old. Dad observe that when bending the back curve out abnormally. The reason is the length of both legs is uneven. The difference is 1 centimeter. This might result in bad body structure and have to go for a surgery in the future. I asked the doctor is there a way to correct it without surgery option or decrease the chance of it. He said yep!!! The way is so new …to me … Finally, he can really solve the problem.
