Living with Plantar Fasciitis: That First Step Pain
Plantar fasciitis is the most common cause of heel pain, affecting approximately 10% of people at some point in their lives. That stabbing pain with your first steps in the morning—or after sitting for a while—is unmistakable. It can turn simple activities like walking to the kitchen into a dreaded ordeal.
The plantar fascia is a thick band of tissue running along the bottom of your foot, connecting your heel to your toes. When this tissue becomes irritated and degenerates from repetitive stress, microtears develop at its attachment to the heel bone. Despite being commonly called 'fasciitis' (suggesting inflammation), it's actually a degenerative condition—which is why anti-inflammatory treatments often provide only temporary relief.
Risk factors include prolonged standing, running, tight calf muscles, obesity, and improper footwear. The condition is notoriously stubborn: while most cases resolve within a year, many people suffer for months with treatments that only mask the pain rather than promote actual healing.
Sound familiar?
- Sharp, stabbing heel pain with first morning steps
- Pain that improves with movement but returns after rest
- Tenderness at the bottom of the heel
- Pain that worsens after (not during) exercise
- Stiffness and aching in the arch of the foot
- Pain when climbing stairs or standing on tiptoes
- Gradual onset that becomes chronic over weeks/months
How Shockwave Therapy Heals Plantar Fasciitis
Extracorporeal shockwave therapy (ESWT) has been studied for plantar fasciitis since the 1990s, with over 48 randomized controlled trials examining its effectiveness. Unlike treatments that simply mask pain, ESWT triggers biological responses that promote actual tissue repair.
Shockwaves stimulate the formation of new blood vessels in the damaged tissue. The plantar fascia has poor blood supply, which is why it heals slowly. Improved circulation brings oxygen and nutrients essential for tissue repair.
ESWT triggers the production of organized collagen fibers to replace the disorganized, degenerated tissue. This addresses the root cause—degenerative changes in the fascia—rather than just reducing symptoms.
Shockwaves can disrupt pain-transmitting nerve fibers and reduce levels of substance P (a pain mediator). This provides both immediate and cumulative analgesic effects over the course of treatment.
Research shows ESWT suppresses inflammatory cytokine synthesis, reducing chronic inflammation that perpetuates tissue damage. This creates an environment more conducive to healing.

What the Research Shows
Plantar fasciitis is one of the most well-researched applications of shockwave therapy. A 2023 meta-analysis reviewed 48 randomized controlled trials, making it one of the most studied ESWT indications.
Meta-Analysis of 48 RCTs (2023)
A comprehensive systematic review identified 48 randomized controlled trials comparing ESWT to corticosteroid injections (14 studies), conventional therapies (19 studies), and sham controls (21 studies). ESWT showed significant pain relief compared to sham treatment and significantly better functional outcomes compared to steroid injections.
ESWT vs PRP: Randomized Controlled Trial (2023)
A randomized trial of 72 patients compared ESWT to PRP injections for chronic plantar fasciitis. ESWT provided faster initial pain relief (day 15), while both treatments significantly improved symptoms. Both were safe with no major adverse effects.
Radial ESWT Efficacy Study (2024)
A study of 40 patients with plantar fasciitis showed both immediate and cumulative analgesic effects from radial shockwave therapy. Efficacy rates of 57.5% were achieved using minimal clinically important difference criteria.
ESWT vs Steroid Injections
Multiple trials show ESWT produces similar pain relief to steroid injections but with significantly better functional outcomes (SMD 0.45, p<0.001). Unlike steroids, ESWT doesn't carry risks of tissue atrophy or rupture with repeated use.
Shockwave Therapy vs Other Plantar Fasciitis Treatments
Understanding how ESWT compares to other options helps you make an informed decision, especially if you've tried other treatments without lasting success.
Rest, Ice, Stretching, Orthotics
Pros
- First-line treatment, often effective
- Low cost, no side effects
- Can be done at home
- Addresses biomechanical factors
Cons
- Takes 6-12 months for full effect
- Requires consistent daily commitment
- Not effective for everyone (10-20% become chronic)
- Doesn't actively promote tissue repair
Corticosteroid Injections
Pros
- Fast pain relief (days)
- Covered by insurance
- Well-established treatment
- Can be diagnostic
Cons
- Temporary relief (weeks to months)
- Risk of plantar fascia rupture
- Can cause fat pad atrophy
- Limited to 2-3 injections per year
- Doesn't promote healing
PRP Injections
Pros
- Promotes tissue healing
- Good long-term outcomes
- Uses your own blood
- Single injection often sufficient
Cons
- Slower initial pain relief than ESWT
- Requires blood draw
- Variable preparation methods
- Usually not covered by insurance
- Injection discomfort
Surgery (Plantar Fascia Release)
Pros
- Definitive treatment for severe cases
- High success rate (70-90%)
- Covered by insurance
Cons
- Last resort after 6-12 months conservative care
- Surgical risks (infection, nerve damage)
- 6-10 week recovery period
- Can destabilize foot arch
- Irreversible
Why Choose Shockwave Therapy?
What to Expect During Treatment
Initial Evaluation
We assess your heel pain, review your treatment history, and confirm the diagnosis. We'll determine if shockwave therapy is appropriate based on how long you've had symptoms and what you've already tried.
Treatment Sessions
You'll be positioned comfortably while the clinician applies ultrasound gel and the shockwave applicator to your heel. The device delivers controlled acoustic pulses to the plantar fascia attachment. Most patients describe it as a tapping sensation with some discomfort at the tender point.
Recovery
You can walk immediately after treatment. Some patients experience mild soreness or redness for 1-2 days. We recommend avoiding high-impact activities for 48 hours after each session but normal walking is fine.
Results Timeline
Many patients notice improvement within 2-4 weeks, with continued improvement over 2-3 months as tissue remodeling occurs. Some feel immediate relief; others have a gradual response. The healing process continues even after treatment ends.
Is Shockwave Therapy Right for Your Heel Pain?
Ideal Candidates
- Chronic plantar fasciitis (symptoms >6 weeks)
- Patients who haven't responded to stretching, orthotics, rest
- Those wanting to avoid steroid injections or surgery
- Active individuals who need faster recovery
- Patients with recurrent plantar fasciitis

- People who want to address the cause, not just symptoms
May Need Alternatives
- • Acute plantar fasciitis (<6 weeks)—try conservative care first
- • Patients with bleeding disorders or on blood thinners
- • Active infection in the treatment area
- • Pregnancy
- • Severe peripheral neuropathy affecting the foot
- • Tumor or malignancy in the treatment area
Frequently Asked Questions
How effective is shockwave therapy for plantar fasciitis?
Research shows efficacy rates ranging from 57% to 92% depending on the study, patient population, and how 'success' is defined. A meta-analysis of 48 RCTs found ESWT significantly reduces pain compared to sham treatment and improves function better than steroid injections. Most patients experience meaningful improvement, though results vary.
Is the treatment painful?
There's some discomfort during treatment, especially when the shockwaves hit the tender spot on your heel. Most patients describe it as tolerable—a strong tapping sensation. The intensity is adjustable, and any discomfort typically subsides immediately after the session. No anesthesia is needed.
How many sessions will I need?
Most protocols involve 3-6 sessions, typically once per week. The exact number depends on the severity and duration of your condition and how you respond to initial treatments. Some patients improve significantly after 3 sessions; others benefit from a longer course.
Can I walk after treatment?
Yes, you can walk immediately. Unlike surgery, there's no immobilization period. We recommend avoiding running or high-impact activities for 48 hours after each session, but normal daily activities including walking are fine.
How does ESWT compare to cortisone injections?
Both provide pain relief, but they work differently. Cortisone reduces inflammation quickly but temporarily, and repeated injections risk weakening the fascia. ESWT promotes actual tissue healing with better long-term functional outcomes. Meta-analysis shows ESWT produces significantly better function scores than steroid injections.
What if I've already tried everything else?
ESWT is actually recommended for cases that haven't responded to conservative treatments like stretching, orthotics, and rest. It's considered before surgery in treatment guidelines. Many patients who come to us have 'tried everything'—and still respond well to shockwave therapy.
Are there any side effects?
Side effects are generally mild and temporary: some redness, minor swelling, or bruising at the treatment site, and possible soreness for 1-2 days. Serious complications are rare. Unlike steroid injections, there's no risk of tissue rupture or fat pad atrophy.
How long do results last?
Because ESWT promotes actual tissue healing rather than just masking symptoms, results tend to be long-lasting. Studies with 12-month follow-up show maintained improvement. However, if the underlying causes (tight calves, improper footwear, etc.) aren't addressed, recurrence is possible.
