What Is an Achilles Tendon Injury?
An Achilles tendon injury can happen to anyone, whether you’re an athlete or just going about your everyday life.
The Achilles tendon is the largest tendon in your body. It stretches from the bones of your heel to your calf muscles. You can feel it -- a springy band of tissue at the back of your ankle and above your heel. It lets you point your toes toward the floor and raise up on your tiptoes.
