What Is a Cortisone Injection in the Foot?
A cortisone injection delivers a powerful anti-inflammatory corticosteroid directly into an inflamed structure in the foot—a joint, tendon sheath, bursa, or soft tissue—to reduce inflammation and pain. The injected solution combines a corticosteroid (triamcinolone, methylprednisolone, or betamethasone) with a local anesthetic for immediate temporary numbness. Cortisone injections are among the most commonly performed procedures in podiatric medicine, providing substantial pain relief for many inflammatory foot conditions including plantar fasciitis, Morton’s neuroma, bursitis, and inflammatory arthritis flares.
Conditions Treated with Cortisone Injections
Plantar fasciitis responds well to cortisone for acute and subacute cases, with 60-80% of patients achieving significant short-term pain reduction. Morton’s neuroma injections reduce nerve sheath inflammation; 60-70% of patients achieve satisfactory relief, and a series of 3-4 injections may provide lasting resolution without surgery. Retrocalcaneal bursitis (between the Achilles tendon and heel bone) responds well to carefully placed injections. Ganglion cysts on the foot can be injected to reduce size and symptoms. Gout and inflammatory arthritis flares respond dramatically to corticosteroid injections. First MTP joint arthritis, ankle arthritis, and subtalar arthritis pain can be temporarily managed with intra-articular cortisone.
What to Expect During the Injection
A foot cortisone injection is typically performed in the office in 5-15 minutes. After skin cleaning, the needle is inserted into the target structure—by palpation or under ultrasound guidance for greater precision. The local anesthetic produces rapid numbness, wearing off in 2-4 hours. The corticosteroid takes 48-72 hours to exert its anti-inflammatory effect, with maximum benefit at 1-2 weeks. Some patients experience a “cortisone flare”—24-48 hours of increased pain as the steroid suspension crystals provoke a brief local reaction before anti-inflammatory effects begin. This is normal and resolves spontaneously. Walking after the injection is generally permitted; some providers recommend reduced activity for 24-48 hours to optimize the anti-inflammatory effect.
How Long Does Relief Last?
Relief duration is highly variable. For plantar fasciitis, a single injection provides an average of 4-8 weeks of significant pain reduction; some patients achieve lasting resolution with one injection when they simultaneously address contributing factors (stretching, orthotics, footwear). For Morton’s neuroma, relief typically lasts 2-6 months per injection. The injection relieves inflammation but does not correct structural problems—without addressing these underlying causes (tight Achilles, poor footwear, mechanical overloading), inflammation typically recurs. Cortisone is most effective as part of a thorough treatment plan rather than as a standalone solution.
Risks and Limitations
Cortisone injections are safe when performed properly, but risks include: fat pad atrophy (thinning of the heel cushioning—risk increases with repeated injections); plantar fascia rupture (uncommon but serious, occurring in approximately 2-4% with repeated plantar fascia injections); skin hypopigmentation (depigmentation at the injection site); temporary blood glucose elevation in diabetics (monitor glucose for 1 week post-injection); and infection (extremely rare with sterile technique). Most experts recommend limiting plantar fascia injections to 1-3 per year; PRP is preferable for patients requiring more frequent treatment or those with recurrent plantar fasciitis.

When to See a Podiatrist
Cortisone injections are most effective when paired with a root-cause fix — orthotic, shoe change, or physical therapy. At Balance Foot & Ankle, we use ultrasound guidance to place every injection exactly in the inflamed space, maximizing relief. And we always discuss the treatment plan that follows, so the pain stays gone.

Frequently Asked Questions
How painful is a cortisone shot in the foot?
Pain levels vary by location. Heel injections for plantar fasciitis are often described as moderately sharp due to the density of plantar heel tissue—some providers apply topical anesthetic or ethyl chloride spray before the injection. Injections into softer tissues (Morton’s neuroma interspace, ganglion cysts) tend to be less painful. The discomfort is brief, lasting only during needle insertion and injection, with rapid relief from the local anesthetic within seconds. The local anesthetic numbs the area immediately, providing temporary pain relief that helps confirm correct injection placement. Most patients who are anxious about foot injections find them more tolerable than anticipated.
How many cortisone shots can I get in my foot?
Most experts recommend limiting cortisone injections in weight-bearing structures to 1-3 per year per site. For plantar fasciitis, repeated cortisone injections increase the risk of fat pad atrophy and plantar fascia rupture. For joint injections (ankle, MTP joints), the conventional recommendation is no more than 3-4 injections in the same joint, as repeated steroid exposure may accelerate cartilage degradation. For Morton’s neuroma, a typical treatment series involves 3-4 injections over 3-4 months; if a series fails to provide lasting relief, surgical excision is considered. If you find yourself needing frequent cortisone injections, this may indicate the underlying cause is not being adequately addressed, and other treatments (PRP, orthotics, physical therapy, surgery) should be reconsidered.
Is cortisone or PRP better for plantar fasciitis?
Both work, but their timing and duration of benefit differ. Cortisone provides faster short-term relief (significant improvement at 4-6 weeks) while PRP provides better long-term outcomes (superior at 6-12 months). Multiple randomized trials comparing the two show cortisone wins at 4-6 weeks but PRP wins at 6 and 12 months, with lower recurrence rates. Clinically, cortisone is the better choice when: fast relief is needed, it is the patient’s first injection, and no prior cortisone injections have been given. PRP is preferable when: the condition is chronic (6+ months), previous cortisone has provided only temporary relief, or the patient has already had multiple cortisone injections and wants more durable treatment. Your podiatrist can help select the best option based on your specific situation.

When should I see a podiatrist?
See a podiatrist if: foot or ankle pain has lasted more than 2–4 weeks without improvement, you’re changing your gait to avoid pain, you have an open wound or sore that isn’t healing, you notice nail discoloration or thickening, you have diabetes and any foot concern, or pain is severe enough to wake you at night. Most foot conditions are easier and cheaper to treat early — what starts as a minor issue can become a surgical problem with months of delay.
What is the difference between a podiatrist and an orthopedic surgeon?
Podiatrists (DPM — Doctor of Podiatric Medicine) specialize exclusively in the foot, ankle, and lower leg. Orthopedic surgeons (MD/DO) have broader musculoskeletal training but variable foot/ankle subspecialization. For foot and ankle-specific problems, a podiatrist often has more focused training and experience. For injuries involving the leg above the ankle, complex pediatric cases, or multi-level reconstruction, orthopedic consultation may be appropriate. We frequently co-manage patients with orthopedic colleagues.
How do I know if my foot pain is serious?
Signs that warrant same-day or next-day evaluation: severe pain that appeared suddenly without clear cause, swelling, redness, and warmth that appeared suddenly (possible gout, infection, or Charcot fracture), an open wound that looks infected (redness spreading, pus, warmth), inability to bear weight, or any foot problem in a diabetic patient. Pain that’s been present for weeks and is stable is important but not an emergency — schedule within 1–2 weeks.
Can foot problems cause back and knee pain?
Yes — this is a kinetic chain effect. Abnormal foot mechanics (overpronation, supination, leg length discrepancy) cause compensatory changes in knee, hip, and lumbar alignment. Roughly 30% of patients presenting to our clinic with knee pain have a treatable foot-level biomechanical cause. Correcting foot mechanics with orthotics or appropriate footwear often provides significant knee and back relief. If you have chronic knee or back pain and haven’t had your foot mechanics evaluated, it’s worth a consult.
Are orthotics worth it?
For the right conditions, yes — custom orthotics are among the most cost-effective interventions in podiatry. They’re most effective for: plantar fasciitis, flat feet with secondary knee/back pain, leg length discrepancy, metatarsalgia, posterior tibial tendon dysfunction, and diabetic foot pressure management. Quality OTC orthotics ($35–60) resolve symptoms for 60% of patients with mild-to-moderate conditions. Custom orthotics are appropriate when OTC options have failed or when the biomechanical problem is complex. We cast custom orthotics in-office.
How do I choose the right running shoes?
Start with your foot type (flat, neutral, high arch) and running pattern (overpronator, neutral, supinator). Flat feet and overpronators do best in stability or motion-control shoes. Neutral feet do well in neutral-cushioned shoes. High arches need maximum cushioning with flexible soles. Always buy running shoes at the end of the day (foot swelling peaks then), get properly fitted by a specialist, and replace every 300–500 miles. If you’ve been injured repeatedly, a gait analysis can identify the mechanical flaw driving your injury pattern.
What is the difference between a sprain and a fracture?
A sprain is a ligament injury (the tissue connecting bones); a fracture is a break in the bone itself. Both can occur with the same trauma (ankle roll, fall). The old test — ‘if you can walk, it’s not broken’ — is wrong; many fractures are initially weight-bearable. Key differences: a fracture typically produces localized bone tenderness along the bone itself, while a sprain is tender over the ligament. X-ray is the standard to differentiate. High-grade sprains without proper treatment can be as disabling as fractures.
How do I prevent foot and ankle injuries?
The four most impactful prevention strategies: (1) Supportive, appropriately fitted footwear for your foot type and activity. (2) Gradual activity progression — the 10% rule (never increase weekly mileage or intensity by more than 10%). (3) Regular calf and ankle mobility work. (4) Strengthening the posterior tibial tendon, peroneals, and intrinsic foot muscles. Most overuse injuries are preventable; most acute injuries are not — but ankle sprain recurrence (60–70% without rehab) is prevented by balance and proprioception training.
