Achilles Tendon Injury: Causes, Treatment & Prevention

The Achilles tendon is the unsung hero of our lower limbs. It quietly powers every push-off, jump, and sprint until something goes wrong. For runners, dancers, and anyone who’s felt that dreaded sting in the back of the heel, this guide is for you.

Let’s explore how to understand, treat, and protect this vital tendon for lifelong movement.

🦵 What Is the Achilles Tendon?

The Achilles tendon links your calf muscles (gastrocnemius and soleus) to your heel bone (calcaneus). It’s the thickest, strongest tendon in the body—and yet, one of the most prone to injury due to its constant use in:

• Walking
• Running
• Jumping
• Climbing stairs
• Standing on tiptoes

🧠 Quick Fact: The Achilles tendon can withstand forces up to 1,000 pounds. But when overworked, even the strongest cable can fray.

⚠️ What Causes Achilles Tendon Injuries?

Achilles tendon injuries usually arise from overuse, sudden strain, or poor conditioning. Here’s what often leads to trouble:

• 📈 Sudden increase in activity (e.g., ramping up your mileage)
• 🏃‍♂️ Chronic overuse in sports like basketball, tennis, or sprinting
• ❌ Inadequate warm-up or stretching
• 👟 Wearing improper or worn-out footwear
• 🦶 Flat feet or limited ankle mobility
• 💉 Corticosteroid injections (can weaken tendons)
• 👤 Age (middle-aged athletes are especially at risk)

🔍 Symptoms of Achilles Tendon Problems

You may first notice a stiff, sore feeling in your heel or calf. If untreated, this can escalate. Look for:

• Morning tightness that eases after walking
• Pain behind the heel during or after activity
• Swelling or thickening of the tendon
• A popping sound at injury (may indicate rupture)
• Weakness when pushing off or rising on toes

🩺 Common Achilles Tendon Conditions

Condition	What It Is	Key Symptoms
Achilles Tendinosis	Degeneration of tendon fibers (not inflammation) from long-term overuse	Swelling, activity-linked pain
Paratendinosis	Inflammation of the sheath around the tendon	Tenderness to touch, swelling
Calcific Tendonitis	Calcium buildup inside the tendon (aka Tendo-Calcinosis)	Severe stiffness, may need surgery
Haglund’s Deformity	Bony growth at back of heel, often from tight shoes	“Pump bump”, pain when wearing footwear
Retrocalcaneal Bursitis	Inflammation of fluid sac between tendon and bone	Swelling, redness, pain in back of heel

🧊 First Response: What to Do in the First 72 Hours

🛑 Rule #1: Stop doing whatever caused the pain.

Apply the R.I.C.E. method:

• Rest: Avoid putting weight on the foot.
• Ice: Apply ice for 10–15 minutes, 3–4x/day.
• Compression: Use an elastic wrap to reduce swelling.
• Elevation: Raise foot above heart level.

💊 Ongoing Treatments & Recovery Tips

Depending on the severity, your doctor may recommend:

• NSAIDs (ibuprofen) for pain (use with medical guidance)
• Heel lifts or orthotics to reduce strain
• Massage therapy (focus on calf muscles, not the tendon directly)
• Physical therapy: Strengthening, stretching, ultrasound
• Walking boot or brace for partial tears
• Surgery: For complete ruptures or chronic damage
