Achilles tendon injury is the most terrible injury for an athlete. It's just that if he damages it at least once in his life, he will suffer with it for the rest of his life. Believe me, I know what I'm talking about. I've been doing gymnastics for ten years and had many injuries. However, the only injury I still suffer from is a damaged tendon. I hurt it in the process of stretching. For the first couple of months, I wore special bandages from https://remaininthegame.ca/product-category/orthopedic-bracing-support/ankle-brace-support/. Then I moved without them, but if I hit the back of my ankle, I experienced a hell of a pain that lasted for two days.
