What is the Achilles Tendon?

The Achilles tendon is the large tendon that connects the calf muscles to the heel bone (calcaneus) and is used when you walk, run and jump. 

What is Achilles Tendon Bursitis?

Achilles tendon bursitis or retrocalcaneal bursitis is a condition that commonly occurs in athletes. It is a painful condition caused by the swelling of the bursa, a fluid-filled sac that is located at the back of the heel under the Achilles tendon. This retrocalcaneal bursa contains a lubricating fluid that acts as a cushion to reduce friction between muscle and bones.
