Achilles Tendonitis

Achilles tendonitis or Achilles tendinitis is a common overuse condition that causes inflammation of the Achilles tendon.Located at the back of the ankle, this large and strong band of tissue connects the calf muscles to the heel.

How Achilles Tendonitis

Develops

The Achilles tendon is active during everyday movements such as walking, jumping, running, and standing on tiptoe. Although it is built to handle significant stress, repeated strain or sudden increases in physical activity can irritate the tendon and lead to Achilles tendonitis.

In most cases, Achilles tendonitis is not caused by a single injury. Instead, it develops gradually due to wear and tear or ongoing overuse. Over time, tiny tears form within the tendon fibers. If stress on the tendon continues, it can become thickened, painful, and weaker, increasing the risk of more serious injury and ongoing Achilles tendon pain.

Types of Achilles Tendinitis

Achilles tendinitis is classified into two types based on the site of inflammation. Both types can develop separately or at the same time.

What Causes Achilles

Tendonitis?

Common causes of Achilles tendonitis include:
  • Sudden increase in physical activity
  • Running on hard or uneven surfaces
  • Tight calf muscles
  • Poor footwear with little heel support
  • Flat feet or abnormal foot mechanics
  • Obesity, which adds stress to the tendon
  • Lack of proper stretching
  • Training without rest days
In many cases, the pain develops slowly and worsens over time.

What Are the Symptoms of

Achilles Tendonitis?

Symptoms may vary depending on severity, but common signs include:
  • Stiffness or pain along the back of the heel or ankle
  • Heel pain that is worse in the morning
  • Pain that increases with activity
  • Swelling or thickening of the tendon
  • Tenderness when touching the tendon
  • Limited ankle movement
Failing to address these symptoms may allow the condition to worsen.

The Complications of

Untreated Achilles Tendinitis

Leaving Achilles tendonitis untreated can lead to serious complications that affect long-term foot function and mobility. While early symptoms may seem mild, ongoing stress on the tendon without proper care can cause lasting damage.

What to Do and Avoid with Achilles Tendinitis?

When managing Achilles tendonitis, certain steps can help relieve pain and promote healing, while other behaviors can worsen the condition.

Do (Recommended)

  • Rest the tendon by pausing activities that increase pain.

  • Apply ice for about 15 minutes, especially after activity or during flare-ups.

  • Wear supportive footwear; consider heel lifts or orthotics to reduce tendon strain.

Don't (Avoid)

  • Don’t push through pain or continue intense exercise with tendon discomfort.

  • Avoid walking barefoot or wearing shoes without proper support.

  • Don’t suddenly increase workout intensity or duration without proper buildup.

How Is Achilles Tendinitis Diagnosed?

Diagnosis begins with a physical exam to check for tenderness, swelling, and how the
foot and ankle move. Pressing on the tendon helps identify the exact area of pain.
Imaging tests may also be used:

X-rays

Can reveal bone spurs or rule out other conditions, but don’t show the tendon itself.

Ultrasound

Shows real-time images of the tendon and can check blood flow.

MRI

Gives a detailed view of the tendon and helps assess the level of damage.

How Is Achilles Tendonitis Treated?

Treatment varies based on how severe the condition is. Many cases respond well to simple, at-home care. For more advanced or persistent symptoms, medical options are available.

Over-the-counter pain relievers can reduce discomfort and swelling.

If conservative care fails or a tear is present, surgery may be required to repair the tendon and restore function.

Note: Always consult a physician to confirm the diagnosis and determine the best treatment plan based on your condition and activity level.

When to Seek Care for Achilles Tendon Pain?
It is important to seek medical evaluation if Achilles tendon pain continues despite rest or home treatment.
Delaying care can allow the condition to worsen and often leads to a longer recovery process.
