Plantar Fasciitis Injection: Cortisone vs. PRP vs. Other Injection Options
A plantar fasciitis injection is one of the most effective tools for getting fast relief from chronic heel pain — but not all injections are the same, and they’re not right for every patient. This guide breaks down the types of injections used for plantar fasciitis, when they’re recommended, what to expect, and how to get the most out of your treatment.
Do Injections Actually Help Plantar Fasciitis?
Yes — when used correctly. Cortisone injections for plantar fasciitis consistently reduce pain significantly in 70–80% of patients in the short term (1–3 months). For patients who have been dealing with chronic heel pain despite stretching, orthotics, and anti-inflammatories, a well-placed injection can break the pain cycle and make other therapies more effective.
However, injections are not a cure. They treat the symptoms (inflammation and pain) rather than the underlying cause (tight calf muscles, flat feet, overuse). Without addressing the root cause, pain typically returns.
Types of Plantar Fasciitis Injections
1. Cortisone (Corticosteroid) Injection — Most Common
A corticosteroid (triamcinolone, betamethasone, or methylprednisolone) combined with a local anesthetic is injected directly into the plantar fascia insertion point at the heel.
- Relief onset: 3–7 days
- Duration: 3–6 months on average
- Limit: Generally no more than 3 injections per year — repeated cortisone weakens the plantar fascia and increases rupture risk
2. Platelet-Rich Plasma (PRP) Injection
Blood is drawn from the patient, spun in a centrifuge to concentrate platelets and growth factors, then injected into the plantar fascia. PRP stimulates tissue healing rather than simply masking inflammation.
- Best for: Chronic plantar fasciitis (6+ months) that hasn’t responded to cortisone
- Relief onset: Slower (2–6 weeks) — healing takes time
- Duration: Often longer-lasting than cortisone
- Cost: Higher; may not be covered by insurance
3. Amniotic/Regenerative Tissue Injections
Uses processed amniotic membrane or fluid containing growth factors and anti-inflammatory properties. A newer option showing promise for chronic, difficult-to-treat cases.
4. Prolotherapy
An irritant solution (commonly dextrose) is injected to trigger a healing inflammatory response. Less commonly used for plantar fasciitis but an option for chronic cases.
Cortisone Injection: Pros and Cons
Pros:
- Rapid pain relief — most patients improve significantly within a week
- Quick in-office procedure (5–10 minutes)
- Low complication rate when performed by a trained podiatrist
- Allows resumption of activity and active physical therapy participation
- Cost-effective and typically covered by insurance
Cons:
- Does not fix the underlying biomechanical cause
- Pain often returns without complementary treatment
- Risk of plantar fascia rupture with repeated injections
- “Cortisone flare” — temporary 24–48 hour pain increase after injection
- Possible fat pad atrophy (heel pad thinning) with repeated use
- Diabetics should monitor blood glucose closely — cortisone can temporarily elevate blood sugar
What to Expect During a Plantar Fasciitis Injection
The procedure is typically done in-office without sedation:
- The heel area is cleaned and may be iced or numbed with a topical anesthetic
- The podiatrist palpates the plantar fascia insertion to identify the most tender spot
- A fine needle is inserted into or near the fascia insertion point at the heel
- Medication is slowly injected — you may feel brief pressure or burning
- Total procedure time: approximately 5–10 minutes
After the injection: Expect soreness for 24–48 hours. Use ice and limit prolonged standing. Most patients resume normal activity within 2–3 days. Avoid high-impact activity (running, jumping) for at least a week.
Getting the Most from Your Injection
Injections work best as part of a thorough treatment plan. Combine your injection with:
- Calf stretching (gastrocnemius and soleus) — 3x daily, especially before first morning steps
- Plantar fascia stretching — toe pulls and towel stretches
- Custom orthotics or quality OTC insoles — to correct biomechanical contributors
- Supportive footwear — no barefoot walking, especially on hard floors
- Night splint — keeps the fascia gently stretched while you sleep
- Weight management — excess weight significantly increases plantar fascia load
When to Consider PRP Instead of Cortisone
PRP is generally recommended when:
- Cortisone has provided only temporary relief over multiple injection cycles
- Symptoms have been present for more than 6 months
- Ultrasound shows significant degeneration (tendinosis) rather than acute inflammation
- You want a longer-term regenerative solution
⚠️ When to See a Podiatrist for Plantar Fasciitis
Plantar fasciitis that doesn’t improve on its own often becomes chronic — and chronic cases are much harder to treat. See a podiatrist when:
- Morning heel pain has lasted more than 4–6 weeks
- You’ve tried stretching and OTC insoles with no improvement
- Pain is severe enough to affect your gait or daily activities
- You have diabetes, obesity, or flat feet (higher risk of complications)
- Pain is worsening rather than stabilizing
- You’re considering whether an injection is the right option for you

More questions patients ask
What causes heel pain?
Heel pain most commonly results from plantar fasciitis, accounting for ~80% of cases. Other causes include Achilles tendinitis, heel spurs, stress fractures, and Baxter's nerve entrapment. Dr. Biernacki performs thorough biomechanical evaluations. Call 810-206-1402 for a same-day appointment.
How long does plantar fasciitis take to heal?
With proper treatment, most cases improve within 6-12 weeks. Options include custom orthotics, stretching, physical therapy, and injections. For persistent cases, Dr. Biernacki offers shockwave therapy and minimally invasive procedures.
Should I see a podiatrist for heel pain?
Yes. A board-certified podiatrist can accurately diagnose heel pain using X-rays and diagnostic ultrasound, ruling out stress fractures. Early intervention leads to faster recovery. Call 810-206-1402.
What injections are available for plantar fasciitis?
Several injection options are available for plantar fasciitis: (1) Corticosteroid (cortisone) injection — most common; 70–80% short-term response rate; reduces inflammation rapidly; risk of plantar fascia rupture and fat pad atrophy with repeated use; (2) Platelet-rich plasma (PRP) injection — regenerative; stimulates tissue repair; superior to cortisone at 6–12 months; better for chronic cases; no rupture risk; slower onset; (3) Prolotherapy (dextrose injection) — promotes tissue repair with less expense than PRP; emerging evidence; (4) Botulinum toxin (Botox) — reduces muscle spasm contributing to plantar fascia tension; used in refractory cases; (5) Amniotic membrane (AMNIO) injection — regenerative with growth factors; (6) Dry needling — without injection — stimulates healing response. At Balance Foot & Ankle in Howell (4330 E Grand River) and Bloomfield Township (43494 Woodward Ave #208) — call (810) 206-1402.
How do I know if I need a plantar fasciitis injection?
Injection therapy for plantar fasciitis is typically indicated when: conservative measures have been tried for 6–8 weeks without adequate improvement (stretching, orthotics, night splints, physical therapy, activity modification), pain is significantly affecting daily activities or work, you need faster pain relief while implementing longer-term mechanical treatments, or you have a specific high-demand event (travel, wedding, sporting event) requiring temporary pain control. Injection is generally not the first treatment recommended — the majority of plantar fasciitis cases (85%+) respond to conservative care within 3–6 months without injections. Recurrence after injection without addressing the mechanical cause is common. At Balance Foot & Ankle, we exhaust conservative options first and use injection therapy strategically — call (810) 206-1402.
Does a plantar fasciitis injection hurt?
Plantar fasciitis injections involve varying levels of discomfort: most patients rate the injection at 3–6 on a 10-point pain scale; the medial heel approach (from the inner side) is significantly less painful than the direct plantar approach (through the bottom of the heel — the most sensitive skin on the body); local anesthetic (lidocaine) is mixed with the cortisone and provides almost immediate numbing after injection; some podiatrists apply topical anesthetic cream before injection; and ice can be applied after to reduce soreness. The plantar heel is typically quite sore for 24–48 hours after injection (especially with PRP, which intentionally provokes an inflammatory response), then significantly improved pain usually follows. Ultrasound guidance allows more precise placement, often requiring a smaller needle and less medication. Balance Foot & Ankle provides comfortable injection experiences — call (810) 206-1402.
How quickly does a plantar fasciitis injection work?
Response timeline varies by injection type: cortisone injection — local anesthetic in the injection provides temporary relief within minutes; significant anti-inflammatory effect develops over 3–7 days; peak relief at 2–4 weeks; lasting relief varies from weeks to months; PRP injection — initial inflammatory response may cause increased soreness for 3–7 days; improvement begins at 4–6 weeks; peak benefit at 3–6 months; more durable than cortisone. The local anesthetic component provides same-day partial relief, but the therapeutic effect takes days to weeks. If pain is completely resolved immediately after injection, that reflects the anesthetic — not the actual treatment response. At Balance Foot & Ankle in Howell and Bloomfield Township, MI, we counsel patients on realistic timelines for each injection type — call (810) 206-1402.
How long does relief from a plantar fasciitis injection last?
Duration of relief from plantar fasciitis injections: cortisone — average 4–8 weeks of significant relief; some patients achieve 3–6 months; a small percentage achieves permanent resolution (likely the cases that would have resolved anyway); relief typically diminishes with each successive injection; PRP — 6–12 months or longer of improved function; clinical trials show PRP patients continue improving at 12-month follow-up while cortisone patients plateau or worsen; PRP's duration advantage makes it cost-effective despite higher upfront cost. For all injection types, durability is significantly improved when mechanical causes are addressed simultaneously: custom orthotics, stretching program, night splints, and appropriate footwear ensure the fascia heals in a supported environment.
