Morton’s Neuroma: Why It Feels Like a Pebble in Your Shoe (and How to Fix It)
You’re halfway through a walk when you stop, shake out your shoe and check for a stone — only to find nothing there. That phantom pebble is the tell-tale sign of Morton’s neuroma, a thickened nerve in the ball of the foot that can make every step feel like you’re standing on a marble.
Morton’s neuroma is one of the most common causes of forefoot pain we see at Peak Performance Institute, and the good news is that it almost always responds to conservative care. In this guide, our podiatry team explains what’s actually going on inside your foot, what triggers it, and how Morton’s neuroma treatment in West Leederville can get you back to walking, running and standing without that burning, numb ache between your toes.
What is Morton’s neuroma, exactly?
Despite the name, a Morton’s neuroma isn’t a tumour or a growth. It’s a thickening of the tissue around one of the small nerves that runs between your metatarsal bones — the long bones of your forefoot — toward your toes. Most commonly it develops between the third and fourth toes, where two nerves join together, leaving the combined nerve a little larger and more vulnerable to being squeezed.
When that nerve is repeatedly compressed or irritated, it swells and thickens. The surrounding tissue can become inflamed too, and the thickened nerve now has even less room to move in the tight space between the metatarsal heads. The result is pain, burning, tingling or numbness — and that strange sensation of a pebble or fold of sock bunched under your foot that simply won’t go away.
What causes Morton’s neuroma?
The underlying problem is pressure on the nerve, and a few everyday habits tend to be the main culprits:
- Tight or narrow shoes. Footwear that squeezes the forefoot together — pointed toes and narrow toe boxes — presses the metatarsal bones against the nerve with every step.
- High heels. Heels shift your body weight forward onto the ball of the foot, dramatically increasing pressure on the forefoot nerves.
- Foot mechanics. Flat feet, high arches, bunions and other structural issues change how load is distributed through the forefoot, overloading the nerve over time.
- High-impact activities. Running, court sports or standing for long hours on hard surfaces contribute to repeated micro-trauma.
It’s also more common in women, which researchers largely attribute to footwear — particularly the combination of high heels and narrow toe boxes.
Symptoms: that “pebble in your shoe” feeling
Morton’s neuroma usually creeps in gradually. You might first notice discomfort only in certain shoes, or after a long walk. Over time, symptoms tend to become more frequent and more noticeable:
- A sharp, burning pain in the ball of the foot
- Tingling, numbness or a “pins and needles” sensation that radiates into the toes
- The feeling of standing on a small pebble or a bunched-up sock
- Pain that eases when you take your shoes off and massage the foot
The classic giveaway? Pain between the third and fourth toes that improves the moment you remove your shoes. If that sounds familiar, it’s worth getting it checked — early Morton’s neuroma responds far better to treatment than a nerve that’s been irritated for years.
How is Morton’s neuroma diagnosed?
A podiatrist can usually diagnose Morton’s neuroma from your history and a hands-on examination. We’ll ask where and when the pain occurs, then palpate the web spaces between your toes and squeeze the foot in a way that often reproduces your symptoms — sometimes with an audible “click” known as Mulder’s sign.
If the picture isn’t clear, an ultrasound can confirm a thickened nerve and help rule out other causes of forefoot pain such as a stress fracture, arthritis or bursitis.
Morton’s neuroma treatment in West Leederville
Here’s the reassuring part: the vast majority of people with Morton’s neuroma improve with non-surgical treatment, and the goal is always to relieve pressure on the nerve and calm the inflammation around it. At Peak Performance Institute in West Leederville, our podiatrists take a stepwise approach, starting with the simplest measures and only moving up if needed.
Footwear changes
The single most effective first step is often the simplest — give the nerve more room. Switching to shoes with a wide, rounded toe box, a low heel and a softer, more flexible sole reduces the compression at the heart of the problem. Many patients feel a difference within days.
Orthotics and padding
Custom orthotics can correct the foot mechanics that overload the forefoot, while a simple metatarsal pad placed just behind the ball of the foot can spread the metatarsal bones slightly and take direct pressure off the nerve.
Injections
If footwear and padding aren’t enough, a corticosteroid injection can reduce the inflammation around the nerve and provide lasting relief. In some cases, we may discuss other injection options. The goal is always the least invasive treatment that does the job.
When is surgery considered?
Surgery is genuinely a last resort. If conservative treatment has been given a fair trial — usually several months — and the pain is still limiting your daily life, then a surgical release or removal of the nerve may be discussed. This is a decision we’ll walk through with you carefully, weighing the benefits against the recovery time and the small risk of numbness in the affected toes.
Get back to walking comfortably
You don’t have to live with that pebble in your shoe. Morton’s neuroma is common, treatable and — when caught early — responds beautifully to conservative care. If you’re in West Leederville or anywhere across Perth and the ball of your foot has been burning, numb or aching, our podiatry team would love to help you find the cause and get you moving comfortably again.
