Shockwave Therapy for Tendon and Heel Pain: What to Expect
By Nova Physical Therapy | North Hollywood, CA | Published October 2026 | Last reviewed October 2026
You've had heel pain every morning for six months. Or your shoulder still aches when you reach overhead, even after rest, injections, and stretching. Someone mentions shockwave therapy, and you wonder whether it's real or just another gadget.
It's a fair question. Shockwave therapy has solid research behind it for some conditions and weak research for others. This article explains the difference, so you can decide whether it's worth exploring.
The Short Answer
Extracorporeal shockwave therapy (ESWT) delivers acoustic pressure waves through the skin to a painful tendon or soft-tissue area. It has been studied most for long-lasting plantar heel pain and calcific shoulder tendinopathy, where it outperforms sham treatment, though it isn't clearly better than other good options. For some conditions, like Achilles tendinopathy, recent research is not supportive. It works best as part of an exercise-based rehab plan, not as a stand-alone fix. In California, you can see a physical therapist for an evaluation without a referral.
What Is Shockwave Therapy?
Despite the name, there's no electricity involved. A handheld applicator sends rapid pulses of acoustic energy through a gel on your skin into the painful area.
There are two main types:
• Radial shockwave. The energy is strongest near the skin and spreads out as it travels. It's commonly used for tendons and fascia close to the surface, like the bottom of the heel or the outside of the hip.
• Focused shockwave. The energy converges at a set depth. It can reach deeper structures and deliver higher intensity to a smaller area.
Researchers still don't fully understand how shockwave works. The leading theory is mechanotransduction: cells respond to the mechanical stimulus with changes in blood vessel growth, tissue remodeling, and pain signaling (Mayo Clinic). The APTA also notes that its exact therapeutic mechanism remains unclear (APTA practice advisory, 2026).
Which Conditions Does Shockwave Help?
The honest answer depends on the condition. Here's where the research stands as of October 2026.
Calcific shoulder tendinopathy (calcium deposits in the rotator cuff)
What the research shows: Shockwave is linked to higher rates of complete calcium deposit resolution. Guidance suggests it may be considered when calcification is present (NICE).
What it means for you: One of the better-supported uses, usually after imaging confirms calcification.
Chronic plantar heel pain (plantar fasciitis)
What the research shows: A review of 48 trials found better pain relief than sham, but no difference versus steroid injection or conventional therapy (HTAi abstract). Another review of 14 trials found reduced fascia thickness but no significant pain advantage over other non-surgical care (Simental-Mendía et al., 2024).
What it means for you: A reasonable option when heel pain lasts months despite good basic care, not a shortcut past it.
Shoulder pain without calcification
What the research shows: Evidence is weaker. NICE-cited recommendations advise against routinely offering shockwave for long-standing shoulder pain without calcific tendinitis.
What it means for you: Exercise-based rehab comes first.
Achilles tendinopathy
What the research shows: A 2026 review of 9 trials found no effect for insertional Achilles pain and inconsistent results for midportion pain, and could not recommend it (JOSPT, 2026). An earlier review found added benefit when combined with tendon loading for midportion pain (Paantjens et al., 2022).
What it means for you: Progressive calf loading remains the core treatment. Shockwave is not a routine add-on.
One pattern runs through all of this: shockwave is a second-line option for stubborn, long-lasting problems. It isn't a first step, and it isn't a replacement for rehab.
Why Shockwave Works Best Alongside Exercise
Tendons and fascia adapt to load. Shockwave may reduce pain enough to make loading more comfortable, but it doesn't build the capacity your tendon needs for running, lifting, or a full workday.
That's why, when shockwave is used, it's typically paired with a rehab plan that includes:
• Progressive strengthening of the involved tendon and surrounding muscles
• Gradual return to the activities that provoke symptoms
• Load management, so you're not doing too much too soon or resting too long
• Footwear, activity, or work modifications when they're relevant
What Does a Session Feel Like?
A typical session takes 5 to 10 minutes of actual treatment time. You'll feel rapid tapping or pulsing, which can be uncomfortable over the sorest spot. Intensity is adjusted to your tolerance.
Treatment usually involves a short series of sessions spaced about a week apart. The exact number depends on your condition and how you respond. Many people notice change gradually over the following weeks rather than immediately.
Side Effects and Who Shouldn't Have It
Shockwave is generally well tolerated. Common, short-lived effects include soreness, redness, mild swelling, or small bruises in the treated area. Serious complications are rare, though cases of tendon rupture and bone injury have been reported, mostly with focused shockwave (Arch Phys Med Rehabil review).
Shockwave is commonly avoided or used with caution in these situations:
• Pregnancy
• Bleeding disorders or blood-thinning medication
• Cancer or tumors in or near the treatment area
• Active infection or open wounds over the area
• Open growth plates in children and teens
• Over the lungs, major blood vessels, or nerves
• Pacemakers or other implanted devices near the treatment area
• A recent steroid injection in the same area
If you're considering shockwave, review your medications and medical history with the licensed provider who would deliver it.
What Happens During an Evaluation at Nova
A physical therapy evaluation looks at how your tendon or fascia handles load and what's limiting your activity. It also screens for findings that need a physician's evaluation.
Your evaluation may include:
• How long symptoms have lasted and what you've already tried
• What makes the pain better or worse
• Strength, mobility, and tendon loading tests
• Walking, squatting, hopping, or reaching tasks relevant to your goals
• Screening for findings that need a physician's evaluation
From there, we build an exercise-based plan around your goals. If you're weighing other options like shockwave or injections, we can explain what the research shows and coordinate with your physician or podiatrist.
About coverage: Many insurance plans consider shockwave investigational for musculoskeletal conditions. Check coverage with your plan and the provider before treatment.
You Can See a Physical Therapist Without a Referral in California
California allows direct access to physical therapy. A PT can evaluate and treat you without a physician's referral for up to 45 calendar days or 12 visits, whichever comes first. After that, a physician or podiatrist needs to sign the plan of care for treatment to continue. Your insurance plan may have its own referral rules, so check your coverage.
When to See a Doctor First
Get medical evaluation promptly for:
• A sudden pop or snap followed by weakness, especially in the Achilles or shoulder
• Inability to bear weight or use the limb after an injury
• Severe swelling, redness, or warmth, especially with fever
• Night pain that doesn't change with position, or unexplained weight loss
• Numbness, tingling, or weakness that is spreading or getting worse
• Heel pain in both feet with morning stiffness in other joints
We screen for these during every evaluation and refer you when findings call for medical assessment.
Frequently Asked Questions
Does shockwave therapy hurt?
It can be uncomfortable over the sorest spot, but intensity is adjusted to your tolerance. Most sessions take under 10 minutes.
How many sessions will I need?
Studies typically use a short series spaced about a week apart. The provider delivering it can give you an estimate.
How fast does shockwave work?
Improvement is usually gradual over several weeks, not immediate. It works best combined with a progressive exercise program.
Is shockwave better than a cortisone shot for plantar fasciitis?
Research shows similar pain results between the two. Shockwave is non-invasive, and the choice depends on your history and preferences. Injections are a decision to make with your physician.
Does shockwave work for Achilles tendon pain?
Recent research is not supportive, especially for pain where the tendon attaches to the heel. Progressive calf strengthening remains the main treatment.
Is shockwave covered by insurance?
Often not, for musculoskeletal conditions. Check with your plan before treatment.
Do I need a referral?
Not to start. California allows direct access to physical therapy, within the limits above.
Schedule an Evaluation
