Achilles Tendinopathy: Causes, Treatments & Self-Care Tips

By Unpain Clinic on October 9, 2025

Introduction

If you wake up and feel that sharp pull in your heel every time your foot hits the floor, you’re not alone. That stubborn, morning stiffness followed by an ache when you walk or run is the calling card of Achilles tendinopathy—sometimes called Achilles tendinitis.

At Unpain Clinic, we meet people every week who’ve tried “resting it,” new shoes, or even cortisone shots, only for the pain to creep back. The good news? This condition can improve dramatically with the right approach.
In this article, written by Uran Berisha, BSc PT, RMT, Shockwave Expert, we’ll cover:

What Achilles tendinopathy really is (and why it’s not just inflammation)
The latest research on what actually works
How we treat it at Unpain Clinic using a full-body approach

Understanding Achilles Tendinopathy

Tendinopathy vs Tendinitis

Decades ago, doctors thought sore tendons were simply inflamed—hence tendinitis. But modern research shows most long-term tendon pain is degenerative, not inflammatory. Under the microscope, we see frayed collagen fibers, disorganized tissue, and fragile new blood vessels, not swelling. That’s why anti-inflammatories or rest alone rarely fix the problem. The tendon needs the right type of loading to remodel and grow stronger.

Two Main Types

1. Mid-portion Achilles tendinopathy:
Pain and thickening about 2–6 cm above the heel. Most common in runners and active adults.
2. Insertional Achilles tendinopathy:
Pain where the tendon attaches to the heel bone, sometimes with a small bone spur.

Both limit your ability to walk, climb stairs, or exercise—but the right treatment plan differs slightly for each.

Why the Pain Keeps Coming Back

Tendinopathy is a perfect storm of overuse, weakness, and poor recovery. Common triggers include:

Sudden increase in training volume or hill running
Tight calves or limited ankle motion
Hard surfaces or worn-out footwear
Weak hips or glutes pushing extra stress down to the ankle
Metabolic issues (like diabetes or high cholesterol)
Age-related changes in tendon elasticity

When the tendon is overloaded repeatedly, its fibers break down faster than they repair. Over time, the structure weakens, the area becomes painful, and your nervous system starts to “guard” the region—making even light activity feel sore.
Breaking that cycle means improving both the tendon’s capacity and your movement mechanics.

What Science Says Works

1. Progressive Loading (Exercise Therapy)

Study after study shows that gradual, heavy loading of the calf–Achilles unit is the number-one treatment.
Eccentric exercises (slowly lowering your heel from a raised position) strengthen the tendon and encourage collagen repair.
Heavy-slow resistance training works just as well for people who prefer fewer reps with more weight.
For insertional pain, we modify exercises to avoid dropping the heel below the step, which compresses the tendon against bone.

In a 2021 British Journal of Sports Medicine review of 29 trials, exercise therapy outperformed all passive treatments for long-term recovery.

2. Shockwave Therapy (ESWT)

Extracorporeal shockwave therapy uses acoustic pulses to stimulate tissue repair and blood flow. A landmark American Journal of Sports Medicine study by Rompe et al. found patients who added shockwave to their exercise program improved faster and reported less pain after 12 weeks than exercise alone.

Later reviews confirmed:

Strong evidence for mid-portion Achilles tendinopathy
Mixed results for insertional cases (works best when combined with exercise)

At Unpain Clinic, we use both radial and focused shockwave—adjusting energy levels and pulse counts to each patient’s tolerance.

3. Manual Therapy & Soft-Tissue Work

Massage, myofascial release, and instrument-assisted techniques help reduce calf tightness, improve blood flow, and make loading exercises more comfortable. Combining manual therapy with exercise has shown better short-term pain relief than exercise alone in some reviews.

4. Extracorporeal Magnetotransduction Therapy (EMTT) & Neuromodulation

These advanced technologies use electromagnetic pulses to influence cellular metabolism and pain signaling. While research is emerging, our clinicians find EMTT helpful for reducing inflammation and improving circulation, especially in chronic cases.

5. A Whole-Body Approach

Focusing only on the sore spot misses the bigger picture. We evaluate how your hips, knees, and core contribute to overloading the Achilles. Often, weak glutes or limited ankle motion are the hidden culprits. Correcting them prevents recurrence once the tendon heals.

How We Treat Achilles Pain at Unpain Clinic

Our approach blends science with individualized care:
1. Assessment first – We test mobility, strength, gait, and posture to pinpoint why your Achilles hurts.

2.Targeted therapies – Based on findings, your plan may include:

Focused or radial shockwave
EMTT for inflammation control
Manual therapy to release calf tension
Progressive exercise prescription

3. Load management – We teach you how much activity is safe and when to rest.

4.Footwear & movement coaching – Small gait or shoe changes can make a big difference.

A typical treatment plan lasts 6–8 weeks, with reassessment every few sessions. Most patients notice meaningful pain reduction within the first month.

A Real-Life Example

A 42-year-old recreational runner came to Unpain Clinic after nine months of right-heel pain. She’d tried rest, stretching, and new shoes—no change.
Our assessment found:

Tight soleus muscle
Weak glute medius
Early heel rise while running

We used four sessions of focused shockwave, soft-tissue release, and a customized loading plan. By week 6, she jogged pain-free for 3 km. At 12 weeks, she was back to 10 km runs and rated her morning pain 1/10 instead of 7/10.
Her success wasn’t luck—it was structure, progression, and consistency.

Home Strategies Between Sessions

Here’s what you can safely do to help your tendon heal:

1. Isometric Calf Holds
Stand on your toes (both feet), shift weight to the sore leg, and hold 45 seconds. Repeat 4–5 times. Great for reducing pain sensitivity.

2. Heel-Drop Loading
Rise with both feet, lower slowly (3–5 seconds) on the sore side. Three sets of 15, once or twice a day. Add backpack weight as tolerated.
For insertional pain, stop at flat ground—don’t drop below the step.

3. Gentle Stretching
Stretch your calves with the knee straight (gastroc) and bent (soleus), holding 30 seconds each, 2–3 times daily. Mild tension is fine; sharp pain is not.

4. Manage Your Load
Follow the “10 % rule”: increase weekly activity volume by no more than 10 %. Replace high-impact runs with cycling or swimming during flares.

5. Footwear Check
Use cushioned shoes with a slight heel lift. Avoid very flat or stiff shoes early on. Orthotic inserts can temporarily reduce strain.

6. Ice After Activity
Apply 10–15 minutes for comfort. It won’t fix the tendon, but it eases post-exercise soreness.

7. Track Progress
Note pain levels each morning and after workouts. Improvement looks like less morning stiffness, greater tolerance to activity, and stronger single-leg calf raises.

Frequently Asked Questions

How long does it take to recover?

Most people feel better in 8–12 weeks with consistent care. Chronic cases can take 6 months or more. Healing is gradual—tendons adapt slowly but surely.

Can I keep running?

Yes, if pain stays mild (under 4/10) and doesn’t worsen next day. If it spikes, switch to cross-training for a while.

Is surgery ever needed?

Only after 6–12 months of failed conservative care. Even then, success depends on post-surgical rehab. Most people avoid surgery altogether.

Does everyone need shockwave therapy?

Not necessarily. It’s most effective for mid-portion cases, especially when exercise alone plateaus. We’ll tell you if you’re a good candidate.

What’s the difference between tendinopathy and tendinitis?

Tendinitis = short-term inflammation.
Tendinopathy = long-term degeneration and overload.
Knowing the difference changes how we treat it.

Should I get an MRI or ultrasound?

Usually not right away. Diagnosis is clinical. Imaging helps only if a tear or rare issue is suspected.

Can it come back?

Yes—but recurrence is rare when you keep your calves strong and progress training gradually. Maintenance exercises twice a week are your best insurance.

The Unpain Clinic Difference

What sets our clinic apart is our whole-body perspective. We ask why your tendon failed, not just where it hurts. Our therapists combine advanced technologies like True Shockwave™, EMTT, and neuromodulation with precise movement coaching to deliver faster, safer results.
Many patients say the biggest relief isn’t just being pain-free—it’s finally understanding their body and knowing how to stay that way.

Conclusion

Achilles tendinopathy can feel endless, but it’s not permanent. Modern research shows that the right combination of progressive exercise, targeted therapies, and movement correction can restore tendon health and confidence. At Unpain Clinic, we don’t chase pain; we uncover why it started and fix it from the ground up.If you’ve been stuck in the “rest–flare–rest” loop, it’s time for a structured plan that actually makes sense.
