There's only one medical treatment available to you that is proven to help. But you'll need a doctor and they will need to agree youre the right candidate. And that is Human Growth Hormone. According to the studies, it only works while youre still growing and your bones haven't fused in your back. I don't recommend this treatment, but it's something to look into if youre really worried about height. This is what Lionel Messi did to grow taller when he was a teenager.
