What Is Morton's Neuroma, and Why Does It Feel Like a Stone in My Shoe?

Key takeaways

• The pain sits in the ball of the foot and often spreads into the toes as numbness or tingling.
• Narrow shoes, high heels and abnormal forefoot loading are the most common triggers.
• Ultrasound is usually the first imaging test. Standing whole-body imaging can show the wider alignment and loading pattern that contributed.
• Most people improve without surgery using footwear changes, metatarsal pads or injections.
• ScanAlign does not diagnose Morton's neuroma directly. It reveals how your overall alignment affects the way your foot takes load.

What does Morton's neuroma feel like?

Morton's neuroma typically feels like a sharp, burning pain under the ball of your foot, right between two of the metatarsal bones. Many people describe it as standing on a marble or a folded sock. The discomfort often gets worse when you walk, especially in tight shoes, and eases when you take them off.

Symptoms can come and go. Some people notice them only during longer walks. Others feel them every time they put on a particular pair of shoes. If you develop sudden weakness, loss of feeling in your foot, or pain that does not ease at all with rest, see your GP, call 111, or attend A&E.

What causes Morton's neuroma?

Morton's neuroma develops when the interdigital nerve between two metatarsal heads is repeatedly compressed or irritated. Over time the tissue around the nerve thickens, and the nerve itself becomes inflamed. Several factors raise the risk.

Your body is a connected chain from your feet to your head. If your arch drops, your knee may rotate inward, and your hip and pelvis compensate further up. All of this changes the way your foot strikes the ground, and those changes can concentrate pressure right where the nerve sits. This is why looking at the foot alone sometimes misses the bigger picture.

Where exactly is the nerve affected?

The nerve runs between the metatarsal heads in the ball of the foot. In most cases the interdigital nerve between the third and fourth toes is the one affected. Less commonly it occurs between the second and third toes.

How is Morton's neuroma diagnosed?

Diagnosis usually starts with a clinical examination. Your clinician may squeeze the metatarsal heads together to reproduce the pain or feel for a characteristic "click" (sometimes called Mulder's click). If imaging is needed, ultrasound is the usual first-line test. It is quick, widely available and good at confirming the thickened nerve tissue.

MRI can also show a neuroma clearly, and it is sometimes used when the diagnosis is uncertain or if your clinician suspects another soft-tissue problem at the same time.

Why does standing alignment matter for Morton's neuroma?

Standing whole-body imaging matters because it shows how your skeleton bears weight in the position that actually causes pain. When you lie down for a standard X-ray, CT or MRI, gravity is removed. Your muscles relax, your arches may lift slightly, and the loading pattern that squeezes the nerve disappears from the picture.

An EOS scan captures your entire skeleton from head to feet while you stand. This reveals the chain of alignment from your pelvis through your knees to your arches and forefoot. If your arch has dropped, or your leg is slightly rotated inward, that shift concentrates pressure onto the metatarsal heads. Understanding this chain helps clinicians address the cause, not just the pain site.

At ScanAlign, weight-bearing standing imaging provides this wider context. It does not replace the ultrasound or MRI that confirms the neuroma. It adds the load picture so that any treatment, whether footwear advice, orthotics and overpronation correction or a surgical plan, can account for the forces going through your foot.

What helps manage Morton's neuroma symptoms?

Most people with Morton's neuroma improve without surgery. The approaches below are commonly recommended by GPs, podiatrists and orthopaedic specialists. ScanAlign is a diagnostic imaging clinic, so we do not provide these treatments. We list them so you can discuss options with your own clinician.

• Wider shoes with a roomy toe box. Giving the metatarsal heads more space reduces nerve compression.
• Lower heels. Reducing heel height shifts load away from the ball of the foot.
• Metatarsal pads. A small pad placed behind the metatarsal heads can spread them apart and relieve pressure on the nerve.
• Orthotics. Custom or off-the-shelf insoles can correct overpronation and redistribute forefoot load.
• Steroid injection. A corticosteroid injection around the nerve can reduce inflammation and pain. Results vary.
• Surgery. If conservative measures fail, surgery to remove the thickened nerve tissue (neurectomy) or to release surrounding structures may be considered.

If your clinician recommends orthotics or surgery, understanding your full alignment through gait analysis and standing imaging helps ensure the solution accounts for the way your whole body loads the foot.
