What Are Ultrasound-Guided Steroid Injections?
Ultrasound-guided cortisone injections are a precise, minimally invasive way to treat chronic foot and ankle pain. They combine corticosteroid medication—commonly called cortisone—with ultrasound imaging to target the exact area of inflammation.
Unlike “blind” injections, which rely on anatomical landmarks and the clinician’s feel, ultrasound guidance allows a podiatrist or chiropodist to see the tissues in real time. This ensures the cortisone reaches the injured tendon, ligament, joint, or nerve exactly where it’s needed.
This combination of precision and anti-inflammatory medication makes the treatment highly effective for conditions like:
Plantar fasciitis
Achilles tendonitis
Ankle arthritis
Neuromas (i.e.: Morton's Neuroma) or nerve irritation
How Cortisone Works
Cortisone is a synthetic steroid that mimics hormones naturally produced by your adrenal glands. Its main job in foot and ankle injections is to reduce inflammation.
Here’s what happens on a cellular level:
Cortisone suppresses inflammatory chemicals called cytokines that cause swelling and pain.
It stabilizes cell membranes in the injured tissue, preventing further irritation.
Cortisone can also reduce nerve sensitivity in the area, which helps decrease pain perception.
By directly targeting the source of inflammation, cortisone helps speed up healing and relieve chronic pain without the need for surgery.
The Role of Ultrasound in the Injection
Ultrasound guidance takes steroid injections to the next level. Using high-frequency sound waves, the clinician can see:
Tendons and ligaments
Inflamed soft tissue
Nerves
Joint spaces
This allows the injection to be delivered exactly where it’s needed, which:
Improves the effectiveness of the medication
Minimizes risk of hitting nerves, blood vessels, or healthy tissue
Reduces discomfort during the procedure
For example:
In plantar fasciitis, the cortisone is placed at the point where the plantar fascia attaches to the heel bone.
In Achilles tendonitis, the cortisone is delivered around the tendon sheath rather than the tendon itself, preventing damage to healthy tissue.
In neuromas, it targets the inflamed nerve sheath precisely, reducing pain without affecting surrounding nerves.
Why It Works: The Science
The combination of corticosteroids and its precise placement is what makes this treatment so effective.
Targeted anti-inflammatory action – By delivering cortisone directly to the inflamed tissue, the body’s natural healing process can work more efficiently.
Reduced tissue trauma – Ultrasound guidance avoids unnecessary needle trauma to surrounding tissue, allowing faster recovery.
Pain modulation – Cortisone temporarily decreases nerve irritation, which lowers pain signals sent to the brain.
Support for chronic injuries – Chronic tendon or ligament injuries often involve persistent inflammation and microtears. Cortisone helps calm inflammation so the tissue can repair itself.
In short, the science is all about precision + anti-inflammatory power: delivering cortisone exactly where it’s needed to calm inflammation, reduce pain, and support healing.
Who Can Benefit from Ultrasound-Guided Cortisone Injections?
This treatment is ideal for people with chronic foot or ankle pain that hasn’t improved with other treatments like:
Rest and activity modification
Custom orthotics or supportive shoes
Physical therapy
Anti-inflammatory medications
It’s especially helpful for plantar fasciitis, Achilles tendonitis, ankle arthritis, or nerve-related foot pain.
Ultrasound guided injections alone won't address any underlying biomechanical issues that caused the pain in the first place. Therefore, it's most effective when combined with other treatments, like custom orthotics, supportive shoes that match your foot type and gait pattern, and physiotherapy.
Bottom Line
Ultrasound-guided steroid injections are a safe, precise, and scientifically backed way to treat chronic foot and ankle pain. By combining the anti-inflammatory power of cortisone with the accuracy of real-time imaging, patients often experience faster relief and better outcomes than with traditional injections.

Plantar fasciitis, a condition that impacts the heel of the foot, is very common but often misunderstood. If you've felt sharp stabbing pain in your heel when you take your first steps in the morning, you might know this condition firsthand. But what does plantar fasciitis mean, and how can you treat it? Let's explore the specifics to help you better understand plantar fasciitis causes and treatments.
What is plantar fasciitis?
Plantar fasciitis happens when the plantar fascia gets inflamed. This thick band of tissue stretches from your heel to your toes along the bottom of your foot. It helps support your foot's arch and handles the stress we put on our feet. When this band gets irritated or swollen, it can lead to pain and discomfort. You'll often feel this pain in your heel area. If plantar fasciitis persists long enough and the initial inflammation (acute phase) subsides, it can become chronic. The chronic phase is characterized by less inflammation and more by tissue degeneration over time.
Causes of plantar fasciitis
Plantar fasciitis is typically caused by overuse and activities that put too much stress on the feet, which ultimately strains the plantar fascia. Such activities include includes running long distances, standing for hours, or playing high-impact sports. Risk factors that can make you especially vulnerable to developing plantar fasciitis include:
Foot structure: Conditions such as flat feet or high arches can lead to unhealthy biomechanics (i.e.: overpronation), which can then can put extra stress on the plantar fascia when you walk.
Improper footwear: Wearing shoes that don't support or cushion your feet well can make you more likely to develop plantar fasciitis. High heels, old shoes, or flimsy footwear without adequate arch support can all contribute.
Getting older: Those aged 40-60 are more prone to plantar fasciitis, but it can happen to anyone at any age. It's one of many age-related changes to the feet we experience as we age.
Your job: Working a job where you have to stand or walk on hard floors for a long time can increase your chances of getting this condition. That's right! Even your career can influence your foot health.
Symptoms of plantar fasciitis
The telltale symptom of plantar fasciitis is heel pain. In addition, you may experience the following:
Quick-hitting pain: Pain is often most severe when you take your first steps in the morning, or after sitting for an extended period. This pain tends to decrease with continued activity but can return after rest.
Sharp pain: Plantar fasciitis-related pain is typically sharp and may be felt near the heel's underside.
Pain post-exercise: While activity may initially relieve the pain, it can worsen after exercise or at the end of the day.
Tenderness: Pressing on the area where the plantar fascia attaches to the heel bone may cause pain.
Treating plantar fasciitis
You may experience pain with plantar fasciitis first thing in the morning.
The good news is that most cases of plantar fasciitis can be managed with conservative treatments. Here are some effective strategies for treating plantar fasciitis:
Rest and ice: Resting and applying ice to the affected area can help reduce inflammation and pain. Aim to ice your heel for 15-20 minutes several times daily. You may also benefit from over-the-counter anti-inflammatories like ibuprofen or naproxen, which can reduce pain and inflammation.
Stretching exercises: Gentle stretching of the calf muscles, Achilles tendon, and plantar fascia can help alleviate tension and reduce pain. Exercises such as the calf stretch, towel stretch, and rolling the foot over a cold bottle or a tennis ball can be beneficial.
Footwear: Wear supportive shoes with good arch support and cushioning. Avoid walking barefoot on hard surfaces, and consider using custom orthotic inserts to provide additional support. Read our dedicated blog post on the best shoes for plantar fasciitis.
Night splints: Wearing night splints can help keep the plantar fascia stretched overnight, which may reduce morning pain.
Avoid high-impact sports and activities: Temporarily reducing or modifying activities that exacerbate your symptoms can help prevent further irritation of the plantar fascia.

Have you walked around downtown Toronto with the feeling that you have a pebble stuck in your shoe? It can turn into a persistent nuisance that negatively impacts your daily exercise or routine. If this sounds like you, you may be experiencing a nerve compression syndrome which affects the nerves located at the base of the toes, called a neuroma.
The most common nerve to be affected is the one found at the ball of the foot, between the third and fourth toes. This nerve is naturally thicker than the rest, putting it at higher risk of developing a neuroma. A neuroma at this specific location on the foot is called Morton’s Neuroma. Irritation of the nerve at this location causes the nerve to enlarge or swell, making it more vulnerable to compressive stresses.
What Are The Symptoms Of Morton's Neuroma?
Localized pain that radiates to the toes when wearing shoes or while walking.
Feeling like you’re walking on a pebble.
Numbing, tingling, or burning sensation in your foot and feeling like you have to take off your shoes to rub it for relief.
Sharp pain in your foot.
Pain that radiates from the ball of your foot to your toes.

What Causes Morton's Neuroma?
It is very likely that the cause of your neuroma is poor foot mechanics, with the most common one being overpronation. Overpronation is the involuntary act of rolling the ankles towards the arches as one walks. As the foot pronates more than it should, the metatarsals also move more than they should. This leads to compression and subsequent irritation of the nerves, resulting in pain and inflammation.
How Can I Treat Morton's Neuroma?
Your goals should be to:
Remove pressures from the area of concern.
Allow the nerve to heal.
Prevent future incidences of discomfort.
In summary, overhauling your footwear can make the biggest difference. Booking an appointment with a qualified foot specialist is a great next step. A chiropodist will perform a biomechanical assessment and gait analysis to identify the root cause of your Morton's neuroma. From there, they can assess your foot type, evaluate your walking pattern, and recommend appropriate footwear.
If underlying biomechanical issues are present, custom-made orthotics may be prescribed to improve foot mechanics, control pronation, and redistribute pressure away from the neuroma. These often include features like a metatarsal dome pad, which helps relieve nerve pressure by gently splaying the metatarsal bones.
For more immediate relief, over-the-counter metatarsal pads can be added to your existing insoles. Choosing shoes with a wider fit, a roomy toe box, and a lower heel can also significantly reduce discomfort and help prevent symptom flare-ups.
Finally, if more conservative treatments aren’t providing relief, ultrasound-guided steroid injections may be considered. This involves delivering a corticosteroid (a powerful anti-inflammatory) directly to the affected area while using ultrasound imaging to precisely target the nerve. By placing the medication exactly where it’s needed, this approach helps reduce inflammation around the nerve and can provide relatively fast, effective pain relief.
