The tendon can become sore, thickened and tender to touch at the back of the ankle or just above, on one or both legs. The condition is called Achilles tendinitis, meaning inflammation in the paratenon. It is an overuse problem which happens mainly to teenagers and adults, but can happen to very young children.

Achilles Tendinitis

What you Feel When you Have Achilles Tendon Injury

Symptoms may appear gradually or suddenly. vFirst thing in the morning there is stiffness in the tendon, which wears off as you move around. There is no pain at rest. The tendon might hurt if you go up and down on your toes barefoot, but in the early stages this pain eases with repetitions. Going up and down on your toes wearing shoes usually causes pain. In the later stages, the tendon hurts when you walk and when there is any kind of pressure against it, for instance if you sit with your ankles crossed.

What are the Causes for Achilles Tendon Injury

If you feel the pain when you wear certain shoes, but not barefoot, the cause is friction from the back of the shoe. Most sports shoes have raised backs, known as heel tabs, as do many normal shoes. It may look low, but if the tab is any higher than the level of the ankle it puts pressure on the Achilles tendon. Boots with stiff seams do the same. Once the problem starts, any shoes which touch the Achilles tendon make it worse.

Other causes or aggravating factors of this type of pain include overtraining; faulty foot mechanics, especially overpronation; pain referred from the hip; poor circulation caused by sitting too long in tight clothing or with your ankles crossed; and hormonal changes in females.

Treatment for Achilles tendon Injury

Any faulty shoes must be discarded or modified by cutting the heel tabs back to the right level. In some cases this solves the problem immediately.

Some specialists offer injections into the painful tendon: if you choose this option, make sure your specialist is an expert, otherwise there is a strong risk of tendon rupture a few weeks later. A more drastic option in chronic cases is surgery to strip the tendon clean of inflammatory material.

The tendon can be strained or suffer a minor tear at its attachment to the calcaneus. Sometimes the bursa between the tendon and the upper part of the bone becomes inflamed. In a chronic problem, spurs may form on the calcaneus. A spur can become detached, forming a focal point of pain. Achilles insertion problems can occur at any age. In children it is often linked to Sever’s disease.

Achilles Tendinitis

What you Feel When you Have Achilles Tendon Insertion Strain

Pain usually comes on gradually, although it can happen suddenly. You feel pain on tiptoeing or running. The heel is tender when you press on it. In the early stages the pain may wear off when you are warmed up, but recurs later during your exercise. The tendon gradually tightens. There is little or no pain at rest unless there is direct pressure on the heel.

Causes for Achilles Tendon Insertion Strain

There is usually excessive strain on the calf in extreme ranges of movement, for instance when you run uphill as fast as you can. Shoes contribute if they have rough, uneven linings round the heel; if the heel counter is soft, tight or not the right shape for your foot; if the sole is hard; or if the heel has worn down unevenly.

Treatment for Achilles Tendon Insertion Strain

Check your shoes and discard any which chafe, if padding does not help. You may benefit from orthotics. Your doctor or specialist may offer you an injection.

Ruptured Achilles Tendon

Brief Outline of Achilles Tendon Strain

Achilles tendon strains can be very painful and take some time to heal. The Achilles tendon, which gets its name from the mythological Greek warrior Achilles, is located in the back of the lower leg over the heel. An injury to this tendon can be debilitating because of its involvement in walking and even balance during weight bearing. Explosive activities such as sprinting and jumping, and those activities that involve pushing against resistance such as football linemen and weight training, contribute greatly to this injury.

Achilles Tendon Rupture

Anatomy and Physiology for Achilles Tendon

The Achilles tendon is the largest tendon in the human body, being approximately 15 cm long, and 2 cm thick. It originates from the musculo-tendinous junction of the calf muscles, and inserts into the posterior aspect of the calcaneus. The tendon is separated from the calcaneus by the retrocalcaneal bursa, and from the skin by the subcutaneous calcaneal bursa. It pulls the foot downward, extending it when the calf muscles contract. The strain can be graded on a scale from 1 to 3.

Grade 1 strain: A stretching or minor tear of the tendon (less than 25% of the tendon.)

Grade 2 strain: Involves more of the tendon fibres (usually 25% to 75%.)

Grade 3 strain: A complete rupture of the tendon.

Ruptured Achilles Tendon


Cause of Achilles Tendon Strain

Abrupt, forceful contraction of the calf muscles; especially when the the muscle and tendon are either cold or inflexible. Excessive force applied to the foot, forcing the foot into the plantar flexion.

Signs and Symptoms of Achilles Tendon Strain

Pain in the Achilles tendon, from mild discomfort in grade 1 strains to severe, debilitating pain in the grade 3 strains. Swelling  and tenderness may also be experienced. Pain when rising on the toes. Stiffness in the calf and heel area after resting.

Complications If Left Achilles Tendon Strain Unattended

A minor tear may become a complete rupture if left unattended. Bursitis and tendinitis may develop from the inflamed tendon rubbing over the heel.

Immediate Treatment to Achilles Tendon Strain

R.I.C.E. Anti-inflammatory medication. Then Shockwave Therapy to promote blood flow and healing. Immobilisation and medical help for complete ruptures.

Rehabilitation and Prevention for Achilles Tendon Strain

Rest is important and a gradual return to activity must be undertaken. Stretching and strengthening the calf muscles is important in rehabilitation and to prevent a recurrence. Warming-up the calf muscles properly before all activities, especially those involving forceful contractions such as sprinting, is essential to prevent strains.

Long-term Prognosis for Achilles Tendon Strain

Due to lower blood supply in tendons, they take longer to heal than the muscle, but with rest and rehabilitation, the Achilles tendon can return to normal function. Complete ruptures occasionally require surgical repair.

Brief Outline of Achilles Tendinitis

Inflammation of the Achilles tendon can be very painful, especially since all of the body’s weight is supported by this structure and the shoe often presses against this area. Repetitive stress to the tendon can lead to inflammation that causes additional irritation, causing more inflammation. Activities such as basketball, running, volleyball, and other running and jumping sports can lead to Achilles tendinitis.

Anatomy and Physiology of Achilles Tendinitis

The Achilles tendon is the largest tendon in the human body, being approximately 15 cm long, and 2 cm thick. It originated from the musculo-tendinous junction of the calf muscles and inserts into the posterior aspect of the calcaneus. The tendon is separated from the calcaneus by the retrocalcaneal bursa, and from the skin by the subcutaneous calcaneal bursa. The tendon crosses the back of the heel, which means it rides over the bone as the muscle contracts and stretches. Repetitive contraction of the muscles in the calf and improper footwear or excessive pronation of the feet can lead to inflammation in the tendon.

Achilles Tendinitis

Right Foot Tendon is Thicker than Left Foot Tendon

Cause of Achilles Tendinitis

Repetitive stress from running and jumping activities. Improper footwear or awkward landing pattern of the foot during running. Untreated injuries to the calf or Achilles tendon.

Signs and Symptoms of Achilles Tendinitis

Pain and tenderness in the tendon. Swelling may be present. Contraction of the calf muscle causes pain; running and jumping may be difficult.

Complications If Left Achilles Tendinitis Unattended

Inflammation in the tendon can lead to deterioration of the tendon and eventual rupture if left untreated. Inflammation may lead to tightening of the tendon and attached muscle, which could lead to tearing.

Immediate Treatment for Achilles Tendinitis

Rest, reducing or discontinuing the offending activity. Ice. Anti-inflammatory medication. Shockwave therapy to promote blood flow and healing.

Rehabilitation and Prevention of Achilles Tendinitis

After a period of rest, usually lasting 5-10 days, gentle stretching and strengthening exercises can be initiated. Heat may be used on the tendon before activity to warm the tendon properly. Adequate warm-up, along with strengthening and stretching exercises for the calves, will help prevent tendinitis of the Achilles tendon.

Long-term Prognosis for Achilles Tendinitis

Tendinitis seldom has lingering effects if treated properly. Tendinitis may take from five days to several weeks to heal, but rarely needs surgery to repair it.
