Key Takeaways:
Morton's neuroma is a thickening of tissue around one of the nerves running to the toes, most often between the third and fourth toes. It produces a distinctive set of symptoms: burning in the ball of the foot, numbness in the toes, and the sensation of a pebble or a bunched-up sock underfoot. These symptoms typically ease within minutes of taking your shoe off. Most cases respond to footwear changes, offloading, and orthotics, and early treatment is considerably simpler than treatment of a neuroma that has been irritated for years.
Patients rarely walk in and say they have nerve pain. They say it feels like their sock has bunched up under the ball of the foot, or like they are standing on a marble, or like the front of the foot is on fire by the end of a shift. Then they reach down, smooth out a sock that was never wrinkled, and the feeling stays. That description is specific enough that it often points toward a diagnosis before the exam begins.
The condition behind it is usually Morton's neuroma. It is one of the more common forefoot problems the podiatrists at St. Cloud Foot & Ankle Center treat, and it is also one of the more frequently misread — patients often assume it is a callus, a stress fracture, or simply what feet do after 40. Here is what is actually happening, and what can be done about it.

What Is Morton's Neuroma?
Morton's neuroma is a thickening of the fibrous tissue surrounding one of the small nerves that travel between the metatarsal bones toward the toes. Despite the name, it is not a tumor. The American Academy of Orthopaedic Surgeons describes it as a thickening of the tissue around the digital nerve rather than a growth of the nerve itself.
The nerve passes through a narrow space beneath a ligament that connects the metatarsal heads. When the forefoot is repeatedly compressed, that space narrows further, the nerve is pinched against the ligament, and the surrounding tissue responds by thickening. The thicker it becomes, the less room there is — which is why an untreated neuroma tends to get worse rather than settle on its own. It develops most often in the third web space, the gap between the third and fourth toes, and occasionally in the second.
What Does Morton's Neuroma Feel Like?
The symptom pattern is what makes this condition recognizable. Most patients report some combination of the following:
- Burning or sharp pain in the ball of the foot that may radiate forward into the toes.
- A sensation of standing on a pebble, a marble, or a bunched-up sock that does not go away when you check.
- Numbness or tingling in the two toes on either side of the affected space.
- Symptoms that build over the course of a day and ease within minutes of removing the shoe.
- A click or a shifting feeling when the forefoot is squeezed from side to side.
Two details are worth noting. First, there is usually no visible swelling or bump. The problem sits between the bones, not on top of them, which is part of why people dismiss it. Second, symptoms are usually one-sided at first. If you are dealing with pain in one foot while the other feels fine, an asymmetrical nerve problem is one of the explanations worth ruling in or out.
What Causes a Neuroma to Form?
Nerve compression in the forefoot rarely has one cause. In most cases, several factors stack up over years:
- Narrow toe boxes and high heels, which push the metatarsal heads together and shift weight forward onto the ball of the foot.
- Repetitive high-impact activity — running, court sports, and long hours standing on hard floors.
- Foot structure, including flat feet, high arches, and bunions, all of which change how load distributes across the forefoot.
- Hammer toes or an unstable second toe joint, which can crowd the adjacent web space.
Occupational load matters as well. Nurses, retail workers, and machine operators frequently notice that foot pain builds through a long shift on a hard surface and resolves overnight, which is the classic neuroma rhythm.
How Is Morton's Neuroma Diagnosed?
Diagnosis starts with understanding your medical history, the history of your foot pain, and a hands-on exam. Squeezing the forefoot from side to side while pressing into the affected web space typically reproduces the pain and sometimes produces an audible click. That finding, paired with the symptom pattern described above, is often enough for a podiatrist to make a diagnosis of Morton’s neuroma.
Imaging is used to confirm the diagnosis and rule out conditions that mimic it. X-rays check for a stress fracture or arthritic changes in the joints, since neither responds to neuroma treatment. Ultrasound or MRI can visualize the thickened tissue directly when the picture is unclear. Nerve symptoms in the foot can also stem from a pinched nerve higher up the leg or from peripheral neuropathy, which behaves differently — it usually affects both feet, follows a stocking pattern rather than a single web space, and does not ease when the shoe comes off. Distinguishing between these possibilities changes the treatment plan entirely, which is why persistent tingling or numbness in the toes is worth having evaluated rather than self-diagnosed.
What Are the Treatment Options for Morton's Neuroma?
Treatment follows a conservative-first sequence. Most patients improve without surgery, particularly when the neuroma is caught before it has been irritated for years.
Footwear Changes and Offloading
The first step is removing the compression. That means a wide toe box, a heel under about an inch, and a sole with enough cushioning to absorb impact at the forefoot. A metatarsal pad placed just behind the affected space spreads the metatarsal heads apart and lifts pressure off the nerve, and it is often the single most effective low-cost intervention. When over-the-counter padding is not enough, custom orthotic devices can be built with the pad positioned precisely for your foot and a shell designed to correct the mechanics driving the compression.
Non-Invasive Therapies
For nerve irritation that has not settled with padding and footwear alone, EPAT shockwave therapy delivers acoustic pressure waves into the affected tissue to stimulate the body's own healing response, and MLS laser therapy uses specific light wavelengths to reduce inflammation around the nerve. Neither requires anesthesia or recovery time, and both are available at our St. Cloud, Becker, Melrose, and Paynesville offices. Response varies by patient and by how long the neuroma has been present.
Injections and Surgical Options
Corticosteroid injections can reduce inflammation around the nerve and provide relief that ranges from temporary to lasting. When conservative care and injections have been exhausted and symptoms still limit daily activity, surgery to release the ligament compressing the nerve or to remove the affected nerve segment is discussed. Removing the nerve leaves permanent numbness in the adjacent toes, which most patients find an acceptable trade for the resolution of pain, but it is a decision that deserves a full conversation rather than a quick one.
When Should You Have Forefoot Pain Evaluated?
Occasional soreness after a long day in dress shoes is not a neuroma. Schedule an evaluation if burning, numbness, or the pebble sensation shows up on most days, if symptoms have persisted more than a few weeks, if pain has started changing how you walk, or if the numbness is spreading rather than staying confined to two toes. MedlinePlus advises contacting a provider for constant pain or tingling in the foot or toes, and that threshold is a reasonable one.
One additional note: anyone with diabetes, neuropathy, or reduced circulation should not wait out new forefoot symptoms or attempt padding at home, since reduced sensation can allow pressure injuries to develop unnoticed beneath a pad or insert.
A neuroma caught early is usually a footwear-and-orthotics problem. A neuroma left alone for five years is often a surgical one. The difference between those two outcomes is generally just how soon someone stops smoothing out a sock that was never wrinkled.
