Achilles Tendinopathy (Achilles Tendonitis)
What is Achilles tendinopathy/tendonitis?
Achilles tendinopathy — sometimes called Achilles tendonitis — occurs when the tendon connecting your calf muscles to your heel becomes irritated or damaged. It’s a common overuse injury, especially in runners, walkers and athletes who train on hard surfaces or increase their activity too quickly.
At Novant Health, we understand how frustrating heel or ankle pain can be, especially when it slows you down. Our foot and ankle specialists are here to explain what’s happening, ease your concerns and guide you toward a recovery plan that fits your lifestyle and goals.
A look at Achilles tendon anatomy
Your Achilles tendon is the strongest tendon in your body. It connects your calf muscles (gastrocnemius and soleus) to your heel bone (calcaneus), allowing you to walk, run, jump and rise onto your toes.
Because it bears so much force with every step, the Achilles tendon can become irritated or weakened over time — especially with repeated stress, tight calf muscles or sudden changes in activity.
When the tendon becomes inflamed or its fibers begin to break down, pain and stiffness often follow.
