Achilles Tendinitis describes damage to your achilles tendon in the area where it attaches to the back of the heel bone. This results in discomfort, pain, and a strain at the back of the heel which can shoot up the back of the leg.
It is often referred to as achilles tendinopathy and achilles tendinosis.
The achilles tendon is a thick, fibrous band and the thickest tendon in the body. It attaches the calf muscles (gastrocnemius and soleus, plus the plantaris muscle) at the back of your leg to the back of the heel bone (calcaneus).
Large amounts of force/strain on the tendon overload it, causing the tendon fibres to become damaged and sustain micro-tears. At its worst, partial tears or even complete ruptures may result.
Many activities can strain the achilles tendon as the tendon is used for every step we take. Common causes include:
One of the greatest causes of developing this tendinitis is ignoring early achilles pain and continuing to exercise in the hopes that it will resolve. When pain occurs in the achilles tendon, it’s important that you stop the activity causing the pain.
Generally, symptoms involve pain and tenderness through the achilles tendon, whether it be at the insertion at the heel or further up the tendon at the back of the heel. Pain ranges from a mild discomfort to a severe pain. Symptoms include:
The first step is to manage the initial painful symptoms using RICE (rest, ice, compression and elevation). It’s important to refrain from the activity that initially triggered the pain so that it doesn’t worsen and become more difficult to manage. From there, we’ll discuss the best treatment plan for you based on your current symptoms and history. These may include:
While the following terms are often used interchangeably to describe pain at the back of the heel from the achilles tendon, achilles tendinopathy and tendinosis describe degenerative changes to the tendon. This means the weakening of the tendon over time, even after inflammation has settled. Tendinitis denotes an inflammatory response (‘itis’) following damage and irritation.
Often in an injury, there is an initial inflammatory response, but after it settles and without adequate care, the degeneration continues to progress. Continued non-inflammatory degeneration following an injury is most commonly referred to as tendinosis. Tendinopathy is more of a general term for tendon degeneration, without specifying the nature of the cause.
Because the achilles tendon has a poor blood supply along the length of the tendon and a good blood supply is essential for effective healing and repair, this means that there is a tendency for the tendon to progress into the degenerative state as opposed to staying ‘inflamed’.
