Understanding Achilles Tendon Injuries: Causes, Symptoms & Treatment

Expert Care at Frenchs Forest Foot Clinic – Your Northern Beaches Podiatry Team

The Achilles tendon is the largest and strongest tendon in your body. It connects the calf muscles to the heel bone and plays a crucial role in walking, running, and jumping. Due to the constant stress it endures, it is also one of the most commonly injured tendons.

Whether you’re an athlete, a casual jogger, or someone who spends a lot of time on your feet, an Achilles tendon injury can severely affect your mobility and quality of life.

Common Types of Achilles Tendon Injuries

Achilles injuries generally fall into three main categories:

1. Achilles Tendinopathy

  • Caused by overuse or degeneration of the tendon
  • Pain and stiffness, especially in the morning or after rest
  • Common in runners and those increasing activity too quickly

2. Achilles Tendinitis

  • Inflammation of the tendon due to repetitive stress
  • Symptoms include swelling, tenderness, and pain during activity

3. Achilles Tendon Rupture

  • Partial or complete tear, often during explosive movement
  • Sudden pain, a “pop” sensation, and difficulty walking or standing

Symptoms to Watch For

You may be experiencing an Achilles tendon injury if you notice:

  • Pain at the back of the heel or just above it
  • Swelling or thickening in the tendon
  • Morning stiffness that improves with movement
  • Difficulty standing on tiptoes or climbing stairs
  • A snapping or popping sound (in cases of rupture)

Common Causes & Risk Factors

Causes:

  • Overuse or high-impact activity
  • Sudden increase in training intensity
  • Poor foot mechanics, such as flat feet or high arches
  • Inappropriate footwear
  • Tight calf muscles or limited ankle mobility

Risk Factors:

  • Middle-aged recreational athletes
  • Lack of warm-up or stretching
  • Previous foot or ankle injuries

Diagnosis and Assessment

At Frenchs Forest Foot Clinic, we conduct a thorough assessment that may include:

  • Your medical history and activity profile
  • Physical examination of the tendon and surrounding structures
  • Biomechanical gait assessments
  • Referral for imaging, such as ultrasound or MRI, if needed

Achilles Injury Treatment Options

Conservative (Non-Surgical) Care:

  • Rest and modification of activities
  • Heel lifts or custom orthotics
  • Stretching and strengthening programs
  • Ice therapy and anti-inflammatory strategies
  • Ultrasound therapy to promote healing

Severe or Chronic Injuries:

  • Immobilisation using a walking boot
  • Referral to an orthopaedic surgeon for tendon rupture cases

Recovery Time & Prevention Tips

Recovery Time:

  • Tendinopathy: Several weeks to a few months
  • Rupture: Multiple months of rehab, especially post-surgery

Prevention:

  • Always warm up before activity
  • Increase training gradually
  • Stretch your calves regularly
  • Wear supportive shoes
  • Seek help early for any foot pain or injury

How to Maintain Long-Term Achilles Tendon Health

Recovering from an Achilles injury is just the beginning. Maintaining long-term tendon health is key to preventing future issues. Here are some tips from the team at Frenchs Forest Foot Clinic to keep your Achilles strong and injury-free:

  • Incorporate strength training: Regular calf raises and eccentric exercises help improve tendon resilience.
  • Stay flexible: Maintain good ankle and calf flexibility with daily stretches.
  • Use proper footwear: Supportive shoes reduce strain on the tendon. If needed, consider custom orthotics to improve foot mechanics.
  • Listen to your body: Don’t push through tendon pain. Early intervention prevents chronic issues.
  • Cross-train wisely: Alternate between low-impact activities like swimming or cycling to reduce repetitive stress.

We also recommend regular check-ups if you have a history of tendon injuries, biomechanical issues, or chronic heel pain.

Frequently Asked Questions (FAQ)

What’s the difference between Achilles tendinitis and tendinopathy?

Achilles tendinitis refers to inflammation of the tendon, usually due to sudden overuse.
Achilles tendinopathy involves degenerative changes in the tendon over time. Both cause pain, but treatment may differ slightly based on the cause.

Can I keep walking or running with an Achilles tendon injury?

It depends on the severity. Mild discomfort may allow for modified activity, but continuing to train on a painful tendon can worsen the injury.
Always consult a podiatrist. Our team at Frenchs Forest Foot Clinic can guide you on safe activity levels and recovery plans.

How long does it take to recover from an Achilles injury?

  • Tendinopathy: Weeks to a few months with consistent care
  • Tendon rupture: Typically 3–6 months, especially if surgery is involved

The earlier you seek treatment, the faster and more complete your recovery is likely to be.

Will I need surgery?

Most Achilles injuries respond well to conservative treatment like physiotherapy, rest, and orthotics.
Surgery is typically only considered in cases of complete rupture or when conservative care fails. We can refer you to an orthopaedic specialist if needed.

How do I know if my foot structure is part of the problem?

Issues like flat feet or poor gait mechanics can place extra load on your Achilles tendon. A biomechanical assessment can help identify and correct these issues early on. Custom footwear or orthotic solutions are often effective.
