A Morton’s neuroma is inflammation on one of the nerves in your feet. It causes pain and can make it feel like you’re stepping on a marble. You can probably manage your symptoms with at-home treatments and over-the-counter pain relievers. Morton’s neuromas aren’t actually tumors — they’re thickening in your existing nerve tissue.
A Morton’s neuroma is inflammation on a nerve in your foot. More specifically, it’s an enlargement in the interdigital nerves between the metatarsal bones that connect your foot to your third and fourth toes (your middle toes closest to your pinkie toe). Some healthcare providers refer to Morton’s neuromas as intermetatarsal neuromas or interdigital neuromas.
If you have a Morton’s neuroma, the affected nerve is thickened and swollen. This can make it painful or hard to walk. You’ll usually feel pain on the ball of your foot, between your toes. It might feel like there’s a stone in your shoe or you’re stepping on a marble.
Visit a healthcare provider as soon as you notice any new pain or swelling in your feet. Getting treatment for Morton’s neuroma is important. The neuroma can become larger and cause permanent nerve damage if it’s not treated.
The “neuroma” in Morton’s neuroma is slightly misleading. Neuromas are noncancerous (benign) tumors that form on nerves throughout the body. They grow extra nerve tissue alongside your healthy regular nerve.
A Morton’s neuroma isn’t new tissue growing on a nerve on your foot. It’s not really a tumor. Instead, your existing nerve tissue swells and thickens. Morton’s neuromas aren’t a symptom of cancer. They also don’t cause cancer.
Morton’s neuromas are common. Experts estimate that around 1 in 3 people has a Morton’s neuroma at some point in their life.

The most common symptoms of Morton’s neuroma include:
Morton’s neuroma symptoms usually get worse over time. You might notice some minor pain at first that goes away with rest or after you take off your shoe and massage your foot. As the inflammation on your affected nerve gets worse, your symptoms will become more noticeable.
Morton’s neuroma pain is usually sharp, stinging or burning. It can also feel like you’re stepping on something. It might feel like:
Morton’s neuromas form when a nerve between your toe bones is irritated and swells. Experts aren’t always certain what causes the inflammation, but they think pressure on your toes, the nerves between them and the ball of your foot is the most common cause. Certain activities may increase your risk of developing a Morton’s neuroma, including:
Certain health conditions that affect your feet might make you more likely to develop a Morton’s neuroma, including:
If a Morton’s neuroma isn’t treated, it can cause nerve damage or chronic pain in your affected foot. Visit a healthcare provider as soon as you notice any Morton’s neuroma symptoms. The sooner a provider diagnoses and treats a Morton’s neuroma, the less likely it is you’ll experience complications.
A healthcare provider will diagnose a Morton’s neuroma with a physical exam. You might need to visit a podiatrist, a healthcare provider who specializes in caring for your feet.
Your provider will examine your feet. Tell your provider when you first noticed symptoms and if any activities or positions make them worse.
Your provider will put light pressure on the spaces between your toe bones. They might ask you to stand, walk or move.
Your provider can usually diagnose a Morton’s neuroma based on your symptoms and a physical exam. A foot X-ray won’t show a neuroma. But it can help rule out other common conditions that cause foot pain, like stress fractures and arthritis.
Your provider might use an ultrasound to take pictures of your nerve and the area around it. If the ultrasound doesn’t give them a clear answer, they may recommend an electromyography procedure. This test measures the electrical activity of your nerves and muscles. It can rule out nerve conditions that can cause symptoms like those of Morton’s neuroma.
Your healthcare provider will suggest treatments that relieve your symptoms and reduce the inflammation in your affected nerve.
The most common Morton’s neuroma treatments include:
Most people don’t need surgery to treat a Morton’s neuroma. Your provider may recommend surgery if other treatments don’t relieve your symptoms or walking is extremely painful. Your provider or surgeon will tell you which type of surgery you’ll need and what to expect.
The most common surgical techniques include:
No, Morton’s neuromas don’t just go away, and you can’t fix one on your own. See a healthcare provider or podiatrist if you have Morton’s neuroma symptoms. They’ll diagnose it and suggest treatments to relieve your pain.
You can take steps to prevent a Morton’s neuroma:
Most people with a Morton’s neuroma are able to find a combination of treatments that relieves their symptoms. You should be able to return to all your usual activities pain-free once your affected nerve is less inflamed. You might have to wear different shoes or change which kind of physical activities you’re doing, but you shouldn’t have any long-term impacts after having a Morton’s neuroma.
Morton’s neuroma symptoms can come back. Talk to your provider if you experience pain and symptoms after treatment.
Visit a healthcare provider or podiatrist if you have:
A note from Cleveland Clinic
