Achilles tendinitis is a common condition that occurs when the large tendon that runs down the back of your lower leg becomes irritated and inflamed.
The Achilles tendon is the largest tendon in the body. It connects your calf muscles to your heel bone and is used when you walk, run, climb stairs, jump, and stand on your tiptoes. Although the Achilles tendon can withstand great stresses from running and jumping, it is also prone to tendonitis, a condition associated with overuse and degeneration.
