Why Do My Achilles Tendons Hurt When I Walk?

Achilles tendon pain is a common complaint among active individuals and can range from mild discomfort to debilitating pain. The Achilles tendon is the largest tendon in the body, connecting the calf muscles to the heel bone. In this article, we will explore the causes of Achilles tendon pain and potential treatment options.

Anatomy of the Achilles Tendon

The Achilles tendon is a thick band of fibrous tissue that attaches the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus). The tendon is responsible for transmitting the force of the calf muscles to the foot, allowing for plantar flexion (pointing the toes) and push-off during walking, running, and jumping.

Causes of Achilles Tendon Pain

Overuse Injury

One of the most common causes of Achilles tendon pain is an overuse injury. This occurs when the tendon is subjected to repetitive stress without adequate time to recover. This can result in inflammation of the tendon (Achilles tendonitis) or degeneration of the tendon (Achilles tendinopathy).

A sudden increase in activity level, such as starting a new exercise program or increasing the intensity or duration of exercise, can also lead to overuse injuries. Individuals who participate in activities that involve jumping, such as basketball or volleyball, are at a higher risk for Achilles tendon injuries.


The Achilles tendon can also be injured due to trauma, such as a direct blow to the tendon or a sudden forceful contraction of the calf muscles. This can result in a partial or complete tear of the tendon.

Risk Factors

There are several risk factors that can increase the likelihood of developing Achilles tendon pain. These include:

Age: Tendons lose their elasticity with age, making them more prone to injury.
Gender: Achilles tendon injuries are more common in men than women.
Footwear: Shoes that do not provide adequate support or cushioning can increase stress on the Achilles tendon.
Biomechanics: Abnormal foot mechanics, such as overpronation (excessive inward rolling of the foot) or supination (excessive outward rolling of the foot), can place additional stress on the Achilles tendon.
Medical conditions: Certain medical conditions, such as diabetes and obesity, can increase the risk of developing Achilles tendon injuries.
Treatment Options

Rest and Rehabilitation

In many cases, Achilles tendon pain can be treated with rest and rehabilitation. This may include avoiding activities that aggravate the pain, using ice or heat therapy, and performing exercises to strengthen the calf muscles and improve flexibility.


Individuals with abnormal foot mechanics may benefit from the use of orthotics, such as arch supports or heel cups. These devices can help to redistribute pressure on the foot and decrease stress on the Achilles tendon.


In severe cases of Achilles tendon injury, surgery may be necessary to repair the tendon. This may involve a minimally invasive procedure to remove damaged tissue or a more extensive surgery to repair or reconstruct the tendon.


Achilles tendon pain is a common condition that can be caused by overuse injuries, trauma, and other risk factors. Treatment options vary depending on the severity of the injury and may include rest and rehabilitation, orthotics, and surgery. By understanding the causes and treatment options for Achilles tendon pain, individuals can take steps to prevent and manage this condition.
