Numbness in your toes can be hard to figure out. It may be caused by something serious, such as diabetes, or something simple, like wearing the wrong shoes.
Most often, numbness in your toes is harmless, but it may be linked to a serious condition.
If you notice any of these red flags, don't wait it out. Early medical treatment can prevent a minor issue from becoming a big one.
Diabetes
Diabetes can cause high levels of sugar and fats in your blood, which can damage nerves, something doctors often call diabetic neuropathy. When it affects your feet, legs, hands, or arms, it's called peripheral neuropathy. As many as half the people with diabetes have peripheral neuropathy.
If diabetes is causing your toes to go numb, you might see other signs of the disease, including:
- Feeling very thirsty or hungry
- Extreme fatigue
- Blurred vision
- Frequent urge to pee
- Cuts and bruises that are slow to heal
If diabetes-related numbness in the toes and other foot problems go untreated, they could lead to major complications, some of which may require an amputation. Have your doctor check your blood sugar level to see whether diabetes might be causing the numbness in your toes.
Morton's Neuroma
A Morton's neuroma is a thickening of tissue around a nerve that leads to the toes. The pressure on that nerve can cause pain in the ball of your foot and numbness in your toes. Activity or certain types of shoes can make it worse.
A doctor can diagnose a Morton's neuroma. Treatment options may include:
- Changing footwear (high heels and tight shoes can cause problems)
- Using shoe inserts
- Taking corticosteroid shots to ease the pain if needed
Metatarsalgia
Metatarsalgia is named after the metatarsals (the long bones in your foot between your arch and your toes) and causes pain in the ball of your foot. It can also lead to numbness or tingling in your toes.
We don't know all the causes of metatarsalgia, but they may include the shape of your foot (high arches, bunions, or curled toes can cause it) and simple overwork. Distance runners are more likely to have metatarsalgia. Being overweight may also play a role.
Metatarsalgia may not need medical care. A change of shoes, shoe inserts, rest, and ice may help. But if these things don't help and the pain and numbness in your toes last more than a few days, it may be time to call your doctor.
Raynaud's Phenomenon
Cold weather or stress can slow the blood flow to the extremities (the arms, legs, hands, and feet) in some people with Raynaud's phenomenon. Toes can become numb and even change colors — turning red, white, or blue.
There are two types of Raynaud's phenomenon:
- Primary: Happens by itself (the cause is unknown) and is generally harmless
- Secondary: Linked to diseases that affect your autoimmune system, such as rheumatoid arthritis or lupus
If it's secondary Raynaud's, you may have symptoms of a rheumatic disease or arthritis that could include:
Your doctor can diagnose Raynaud's and check for other diseases linked to it. Most treatments for Raynaud's usually don't include medications, but in severe cases, doctors may prescribe some.
Guillain-Barré Syndrome
Guillain-Barré syndrome is an immune system disorder in which the body's immune system attacks the nerves. It damages the covering around your nerves, which can cause numbness in your toes.
If Guillain -Barréis making your toes numb, you might also have:
- Weakness in your legs that spreads to your upper body
- A hard time making facial movements or moving your eyes
- Rapid heart rate
- A hard time breathing
- Changes in blood pressure
- Pain that becomes worse at night
Guillain-Barré is a rare disease, but it's serious. It can spread rapidly. You should get emergency help if you have:
- Any tingling or numbness in the toes that spreads upward in your body
- Weakness of any part of your body that's spreading rapidly
- Trouble breathing while lying down
More Causes
Other medical issues that can cause numbness in your toes include:
- Stroke
- Brain or spinal cord injury
- Multiple sclerosis
- Infections, such as Lyme disease or syphilis
- Side effects of chemotherapy
- Vitamin B12 deficiency
Takeaways
Toe numbness usually results from something simple (such as tight shoes, certain sleep positions, or sitting on your feet), which resolves quickly once pressure is relieved. But it can also happen because of something more serious, such as nerve compression, poor circulation, or diabetes-related nerve damage, especially if it's persistent, affects both of your feet, or comes with pain and weakness. One-sided numbness tends to point to something like your footwear or a pinched nerve, while bilateral numbness may signal a broader nerve or circulation issue that needs to be checked by your doctor.
FAQs About Toe Numbness
Why do my toes go numb while running or using the elliptical?
Your toes may go numb from tight shoes, tight laces, or repetitive pressure on the nerves in your feet. Try loosening your laces and make sure there is about a thumb’s width of space in the toe area of your shoes.
Can sleeping in certain positions make my toes numb?
Yes. Sleeping positions that put pressure on your nerves or limit circulation (like tucked legs, tight bedding, or sleeping on your feet) can cause temporary toe numbness that resolves within minutes of moving. It's usually harmless "pins and needles" as blood flow and nerve signals are restored to normal.
Why are my toes numb on only one foot?
Usually because of something localized, such as nerve compression from your sleep position, tight shoes, or a pinched nerve on that side.
What kind of doctor should I see for persistent toe numbness?
Start with your primary care doctor. They can run basic tests and refer you to a podiatrist, neurologist, or vascular specialist depending on the cause.
