Shockwave Therapy for Plantar Fasciitis: Does It Work for Chronic Heel Pain?

If stretching, supportive shoes, activity changes, and rehabilitation have not settled your plantar fasciitis, you may eventually hear about shockwave therapy for plantar fasciitis. The name can sound more dramatic than the treatment actually is. Extracorporeal shockwave therapy, commonly shortened to ESWT, is a non-surgical treatment in which controlled acoustic pressure waves are delivered through the skin to the painful area around the plantar fascia.

It is usually considered for persistent or chronic plantar fasciitis that has not improved enough with appropriate conservative treatment. Some patients experience meaningful reductions in heel pain after ESWT, while others notice little improvement. Research results vary, partly because different studies use different machines, energy levels, treatment schedules, and patient groups.

For a broader look at first-line and advanced treatments, see our main guide to plantar fasciitis treatment.

What Is Shockwave Therapy for Plantar Fasciitis?

Shockwave therapy uses a handheld device to send acoustic or pressure waves into the painful tissues around the heel. The treatment does not involve a surgical cut, and nothing is implanted into the foot. 

Researchers are still studying exactly how ESWT produces its effects. It is thought that the mechanical stimulation may influence tissue repair processes and pain signalling, but the precise mechanism is not completely understood. For patients, the important distinction is simple: Shockwave therapy is designed to encourage improvement in a stubborn condition without requiring an operation.

When Is Shockwave Therapy Usually Considered?

ESWT is generally not the first treatment offered when plantar fasciitis has been present for only a few days or weeks. Most people should first receive a structured conservative treatment program that may include:

• Reducing activities that repeatedly aggravate the heel
• Plantar fascia-specific stretching
• Calf stretching
• Progressive foot and ankle strengthening
• Supportive footwear
• Taping or appropriate orthotic support when useful

Some clinical services consider ESWT particularly when symptoms have persisted for approximately six months or longer, although the exact timing varies between clinicians and healthcare systems.

Who May Be a Good Candidate for ESWT?

A patient may be considered for shockwave therapy when:

• The diagnosis of plantar fasciitis is reasonably clear
• Heel pain has become persistent or chronic
• Appropriate stretching and rehabilitation have already been tried
• Activity modification and footwear changes have not provided enough relief
• Pain continues to affect walking, work, exercise, or daily life
• The patient wants to explore a non-surgical option before considering surgery

Before escalating treatment, it is also important to reconsider whether the pain really is plantar fasciitis.

Focused vs Radial Shockwave Therapy

You may see two terms when researching ESWT:

Focused Shockwave Therapy

Focused ESWT directs acoustic energy toward a more concentrated treatment area and can reach deeper tissues depending on the device and settings.

Radial Shockwave Therapy

Radial treatment produces pressure waves that spread more broadly through the superficial treatment area. Both approaches are used for plantar heel pain. Research has not established one universal shockwave protocol that is best for every patient. Treatment results can depend on the type of device, energy level, number of impulses, treatment frequency, and individual patient characteristics.

What Happens During a Shockwave Therapy Session?

The procedure is usually performed in an outpatient setting. A typical appointment may involve the following steps:

1. The clinician identifies the painful area around the plantar fascia.
2. Gel is placed on the skin to help transmit the pressure waves.
3. A handheld shockwave device is positioned over the painful region.
4. The machine delivers a series of controlled impulses.
5. The intensity may be adjusted according to the treatment protocol and your comfort.

Does Shockwave Therapy Hurt?

It can be uncomfortable. Many patients describe repeated tapping, pulsing, or sharp sensations over the tender area. The discomfort often depends on:

• How sensitive the heel is
• The energy level being used
• The type of shockwave device
• The location being treated

If the treatment becomes difficult to tolerate, the clinician may be able to adjust the settings. High-energy treatment may sometimes require additional pain-control considerations, but this varies by technique.

How Many Shockwave Sessions Are Needed?

There is no universal number of treatments for plantar fasciitis. Some commonly used clinical protocols involve approximately three treatment sessions, often spaced about one week apart, while other protocols use different schedules. The number of sessions should therefore be based on the device, treatment protocol, symptoms, and clinician's assessment rather than assuming that every patient needs exactly three treatments.

How Quickly Does Shockwave Therapy Work?

Shockwave therapy should not usually be viewed as instant pain relief. Some people notice improvement relatively early, while others experience gradual improvement over several weeks after the treatment course.

Certain NHS clinical protocols advise patients that meaningful pain reduction may become noticeable around 6 to 12 weeks after treatment, although individual responses vary considerably. That delayed response is important when judging whether the procedure has worked. Having pain the day after the first session does not necessarily mean the treatment has failed.

Does Shockwave Therapy Actually Work for Plantar Fasciitis?

The most accurate answer is: It can help some people, but the results are not equally strong for everyone. Recent research has found improvements in pain and foot function in patients receiving ESWT, and some analyses have found better outcomes than placebo.

However, studies differ considerably in:

• The type of shockwave used
• Energy intensity
• Number of treatment sessions
• Duration of plantar fasciitis
• Comparison treatments
• How treatment success is measured

Shockwave Therapy vs Steroid Injection

Both treatments may be discussed when plantar fasciitis remains painful despite simpler measures, but they work differently.

A 2024 systematic review comparing the two treatments found that ESWT produced better mid-term pain and functional outcomes than corticosteroid injection in the included studies. However, that does not mean shockwave therapy is automatically better for every patient.

Shockwave Therapy vs Surgery

One of the main attractions of shockwave therapy is that it can be considered before surgery in persistent plantar fasciitis. ESWT does not require an incision and generally allows patients to continue basic daily activities.

Surgery, such as partial plantar fascia release or gastrocnemius recession, is usually reserved for a small group of patients who remain significantly symptomatic despite prolonged nonsurgical treatment.

So ESWT often occupies a middle position: Rehabilitation first → selected advanced nonsurgical treatments such as ESWT → surgery only if prolonged conservative care fails.

What Are the Side Effects of Shockwave Therapy?

Most reported side effects are temporary and occur around the treatment area.

They may include:

• Pain or tenderness
• Temporary increase in heel pain
• Redness
• Bruising
• Mild swelling

Less commonly, altered sensation or soft-tissue irritation may occur. Serious complications appear uncommon, but no procedure is completely risk-free.

Can You Walk After Shockwave Therapy?

Many patients can continue light everyday walking after treatment. However, clinicians may recommend temporarily avoiding high-impact activity, long walks, running, or jumping immediately after a session. 

Some protocols recommend reducing impact activity for approximately 24–48 hours. Always follow the instructions provided for the specific ESWT system and treatment plan being used.

Who Should Not Have Shockwave Therapy?

ESWT is not suitable for everyone. Eligibility should be screened by the treating clinician, particularly if you:

• Are pregnant
• Have a bleeding or clotting disorder
• Take anticoagulant or certain antiplatelet medication
• Have an infection or open wound in the treatment area
• Have a tumour or malignancy near the treatment site
• Have certain implanted cardiac or electronic devices
• Have recently received a corticosteroid injection in the same area
• Have an acute plantar fascia tear or another significant local injury

Contraindications can vary according to the device and treatment protocol, so medication and medical history should always be reviewed before treatment.

Should You Stop Stretching and Strengthening After ESWT?

Usually, shockwave therapy should not replace rehabilitation. A common mistake is to treat ESWT as though the machine will fix the foot while everything else can stop. Persistent plantar fasciitis often still requires attention to:

• Plantar fascia flexibility
• Calf flexibility
• Foot and ankle strength
• Footwear
• Walking or running load

Some services specifically provide shockwave therapy alongside an active rehabilitation program. Your clinician may temporarily modify certain stretches or exercises immediately around treatment sessions, so follow the specific post-treatment instructions you receive.

Is Shockwave Therapy Worth Trying?

ESWT becomes most reasonable when the question is not: “I developed heel pain two weeks ago—should I get shockwave therapy?”

but rather: “I have persistent plantar fasciitis, I have genuinely completed appropriate rehabilitation, and my heel is still significantly limiting me. What nonsurgical options remain?”

In that situation, shockwave therapy may be worth discussing. It offers a non-surgical treatment option with generally temporary local side effects, but patients should understand that improvement is not guaranteed.

When Should ESWT Not Be the Next Step?

Before moving to shockwave therapy, reconsider the treatment plan if:

• You have only had symptoms for a short period
• You have not yet tried an appropriate stretching and strengthening program
• Your activity continues to repeatedly overload the painful heel
• The diagnosis is uncertain
• The pain has unusual features such as numbness, severe swelling, or significant night/rest pain

In these situations, confirming the diagnosis or improving basic rehabilitation may be more useful than immediately escalating treatment.

The Bottom Line

Shockwave therapy can be a useful nonsurgical option for selected patients with persistent plantar fasciitis, particularly when several months of appropriate conservative treatment have not provided enough relief.

The procedure delivers acoustic pressure waves through the skin to the painful plantar fascia and usually requires no incision or lengthy recovery period. Some research shows improvements in pain and foot function, but results vary and there is still no universally accepted treatment protocol or guaranteed success rate.

ESWT therefore makes the most sense as part of a treatment pathway—not as an instant replacement for stretching, strengthening, supportive footwear, and appropriate activity management. For someone with newly developed plantar fasciitis, simpler conservative treatment usually comes first.

For someone with persistent heel pain despite a well-followed rehabilitation program, ESWT may provide a reasonable step to discuss before considering more invasive treatment.
