Achilles Tendonitis
in Toronto, Mississauga and Brampton

What Is Achilles Tendonitis?

The achilles tendon is the large tendon which exists at the back of the ankle just below the calf muscle. When this tendon becomes inflamed due to overuse or injury, it is called achilles tendonitis.

It is one of the most common tendon injuries which should always be treated as early as possible. Left untreated, further achilles tendon injury or, worse, achilles tendon rupture can occur.

Achilles tendon injuries can be quite debilitating. It is usually associated with swelling and pain upon tensioning or squeezing of the achilles tendon at the back of the ankle.

What Causes Achilles Tendonitis?

There are several factors that can contribute to achilles tendonitis, the most common being overuse of the muscle/tendon following initial injury to the achilles tendon.

A poorly functioning foot can cause the heel to shift outwards and "bow" the Achilles tendon. This damages the tendon sheath, resulting in painful inflammation of the area. This abnormality needs to be neutralised using orthotic devices, orthoses or foot orthotics to stop recurrence of injury.

A sudden increase in training, excessive hill running and speed work can also cause tearing of the achilles tendon.

Excessive heel cushioning and air-filled shoes can, over a period of time, lose their stability if worn incorrectly. This can cause the heel to sink into the shoe, while the shoe is absorbing shock. This further stretches the Achilles tendon at a time when the leg and body are moving forward over the foot, thereby increasing strain.

Tight calf and hamstring muscles may contribute to prolonged achilles tendonitis due to the continual "pulling" strain they exert on the tendon.

How Is Achilles Tendon Injury Treated?

Achilles tendonitis is a condition that responds well to conservative treatment if treated early. If disregarded, symptoms and treatment can last for several months.

Conservative treatment involves:

Training modification.

Your training schedule should be reduced to enable healing of the damaged area. This helps to allow successful and effective treatment administration.


Rest, Ice, Compression and Elevation. As with any acute injury the RICE principle is paramount.

Rest with your leg elevated above the level of the heart whenever possible in the first 72 hours after injury.

Ice or cold compression should be used in the first three days. DO NOT use heat or massage in the first 72 hours as this can make things worse.

Compression is necessary in the early stages of treatment to help fight the inflammation.

Heel raises.

These help decrease the strain and load on the achilles tendon.

Correction of abnormal body mechanics.

Orthotic devices are designed to allow the foot to function around its normal position, allowing the Achilles to recover and prevent recurrence of the injury.

Stretching and physical therapy.

Mild stretching, massage and strengthening exercises are prescribed to restore the extensibility of the tendon, increase strength and hasten full recovery.

Anti-inflammatory medication.

This may also be required during the initial treatment.
