Achilles Tendonitis

Orthopedic Health Across Your Lifespan

Achilles tendonitis, also spelled tendinitis, is a common overuse injury characterized by pain along the tendon running from the back of the leg to the heel. This condition affects the Achilles tendon, the largest and thickest tendon of the human body, which connects the calf muscles to the heel bone.

Causes of Achilles Tendon Pain

Repetitive overuse is a common trigger and can cause small tears in the tendon. The body’s attempt to repair this damage can lead to heel pain and Achilles tendonitis, or inflammation of the tendon. Achilles tendon injury is common among: 

  • Runners or athletes who suddenly add intense hill workouts or increase running mileage and speed 
  • Workers with jobs requiring long hours on one’s feet or frequent stair climbing
  • Weekend warriors who typically work a sedentary job during the week and do strenuous physical activities like basketball or tennis on their days off

Contributing Risk Factors

Other contributing factors can predispose a person to the injury. Some possible elements that cause heel pain extending to the calf muscles include:

  • Biomechanical issues, such as having flat feet or very high arches.
  • Chronically tight calf muscles. 
  • Worn-out athletic shoes or footwear. 

Common Achilles Tendonitis Symptoms

Achilles tendonitis is often confused with or grouped with other conditions, such as tendinosis, a chronic, non-inflammatory degeneration of a tendon. Although these conditions fall under the same general umbrella, tendonitis has distinct characteristics.

Common signs to look out for: 

The hallmark is pain and stiffness along the tendon, especially upon taking the first steps in the morning. This pain often lessens with mild activity but then worsens after prolonged exercise.

The pain tends to be reported as most intense a few centimeters above the heel bone.

The area may show noticeable swelling or a persistent lump. It is often very tender when touched or squeezed.

In chronic cases, the injured part of the tendon may feel thicker or have a palpable lump compared to the uninjured side.

How Achilles Tendonitis Is Diagnosed

Getting a diagnosis is the first step toward a solution. Treatment starts with a thorough evaluation by a specialist to confirm the diagnosis and rule out other issues. 

  • Patient history: A doctor will begin by asking about the onset and nature of the pain, as well as recent changes in activity and exercise routines.
  • Physical examination: A provider will gently press on the tendon to find the point of maximum tenderness, check for swelling or lumps and assess the ankle’s range of motion and flexibility. The doctor may ask the patient to stand on their toes to test the tendon’s integrity.
  • Imaging studies: While imaging tests are not always necessary, these can be used to rule out other conditions or to assess severity. X-rays can help reveal if the lower part of the tendon has calcified. Magnetic Resonance Imaging (MRI) and ultrasound can provide detailed images of the soft tissue, showing tendon thickening, damage or tears. 

Nonsurgical Achilles Tendonitis Treatment Options

Many cases can improve with nonsurgical treatment. Common nonsurgical treatments for Achilles tendonitis include:

The Rest, Ice, Compression and Elevation steps are often used to manage acute pain and reduce swelling.

Temporarily switching from high-impact activities to low-impact exercises may help reduce strain on the Achilles tendon.

A physical therapist may recommend a program that includes eccentric strengthening and stretching exercises.

Simple heel lifts or custom-molded shoe inserts can help cushion the heel and correct alignment issues such as overpronation, which happens when the foot rolls inward too much while walking.

Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, can help reduce pain and swelling.

When to See a Doctor

Seek medical advice if there is a sudden “pop” at the time of injury, if the pain persists or becomes severe after several days and if walking or daily routine is affected.
