Why Is My Big Toe Numb?

POSTED ON IN Back/lumbar Foot BY Chris Centeno

It might seem like a little thing. Your big toe numb. Is it a big deal? After all, it’s just a big toe. However, does this mean something?

Why Is My Big Toe Numb? It Could Be a Warning Sign of Something Bigger

If your big toe is numb, or if you are having on-again, off-again episodes of numbness, consider this as a warning sign that something bigger is going on. One of those bigger things that can make your big toe numb is a pinched or irritated nerve in your low back. Big toe numbness can also be caused by things like poor circulation or even a pinched nerve between the toes themselves, but it’s more commonly due to a nerve, specifically the L5 spinal nerve in the lower back as this is the nerve that branches all the way from the spine down to the big toe.

But wouldn’t my back hurt if I had a pinched nerve in my low back? Not necessarily. The numbness in the big toe could be that first early-warning sign, and if it isn’t addressed back pain or stiffness might develop. On the other hand, you could have a pinched nerve in your low back and not experience back pain or other back symptoms.

What can cause the L5 spinal nerve to become pinched or irritated? There are a number of things. A bulging or herniated disc. An injury to the back. Even inflammation from arthritis pressing on the nerve. Any of these conditions can cause the foramen, the tunnel that travels out of the spinal column and houses the spinal nerve, to narrow. This narrowing is called foraminal stenosis, and it can cause spinal nerves to become pinched. So if one of these issues has made your big toe numb, having the spinal nerve nonsurgically addressed with PT or an injection of platelet growth factors sooner rather than later will save you a lot of headache in the long run.

Ruling Out Other Issues That Can Affect the Big Toe

Other issues that can affect the big toe include arthritis in the toe itself, tendon injuries, and bunions, so if there are other symptoms accompanying numbness, these should be ruled out. While arthritis is unlikely to make the big toe numb, it can cause pain and stiffness, and it, too, can disrupt how you walk. Unfortunately, the surgical solutions for arthritis in the big toe include fusing toe bones together or amputating and replacing the toe joint, both of which are big surgeries with lengthy recoveries and can cause more problems down the line. Nonsurgical regenerative medicine solutions should be considered before surgery.

An injury to the flexor hallucis longus tendon, which runs along the bottom of the big toe, can be debilitating and extremely painful. Injuries to this tendon can disrupt the ability to flex the big toe and also disrupt ankle stability as well as many other issues. Again, you are more likely to feel intense pain with an injury such as this rather than numbness.

When chronically irritated, the low-back nerves that can make your big toe numb can also cause a bunion, or bone spur, to form on your big toe. Numbness, tightness, and pain are all signs throughout the leg and foot that can accompany this issue. It’s best to treat this problem very early, before surgery becomes the only solution.

The upshot? In order to understand what is making your big toe numb, it’s important that you don’t procrastinate on having it examined. Acting early will allow you to rule out other issues that can affect the big toe, focus in on the root cause of the numbness, and find regenerative solutions to treat it before it gets worse.

    Benjamin,
    In order to help, we'd need to examine you to diagnose the problem. An L5 spinal nerve, a flexor hallucis longus tendon issue, or a bunion which is a bone spur, can cause these types of symptoms, but we wouldn't know in your particular case without examining you. These are the Doctors who can do that type of exam: https://www.regenexx.com/find-a-physician/

    My left big toe and right index finger are numb, Bunions are starting to form. My left calf feels tight and with a slight bulge. There's a pain in my lower back (left side). I have scoliosis (right) which was diagnosed years back. correction: That’s back pain in my lower right side

    Alicia,

    The side to side curving of the spine in Scoliosis can result in a compressed spinal nerve which is often the cause of those types of symptoms. We'd need more information and an MRI to see what's going on in your particular case. If you'd like us to weigh in, please submit the candidate form here: https://www.regenexx.com/the-regenexx-procedures/back-surgery-alternative/

    I have had left big toe numbness off and on but daily for years. My Primary sent me to a foot doctor who said I had arthritis and gave me an simple shoe insert which has done nothing! I also have what I thought were bunions on both feet - she said it is the arthritis. I fell twice on ice when I was young (in 60s now) and broke my tail bone - could that me related. Also I have very flat feet and usually go barefoot most of time because shoes hurt.

    Cynthia,
    Bunions are most often caused by foot pronation, which is caused by a low back issue. Please see: https://www.regenexx.com/bunion-removal-without-surgery/ and https://www.regenexx.com/how-your-back-is-causing-your-bunions/ and https://www.regenexx.com/bunion-surgery-alternatives/ To see what's going on in your particular case, we'd need to examine you. If you'd like to do that, please submit the "Are You a Candidate" form, or give us a call.

    So you say to see a doctor as soon as possible, but like some of these comments said, the doctor gives them something that doesn't work. I refuse to go to the doctor until they can tell me what is wrong with me instead of "practicing" medicine on me. I broke my left foot 6 years ago and it took three doctors AND a radiologist, three weeks to figure out that I broke the cuboid bone in my foot. Then when I developed a blood clot, not only did the doctor not read my chart to realize that I was a pack a day smoker, every person that took blood from me had to butcher me to the point that I looked like a junkie. I have not had blood drawn since. And that was 6 years ago. Any suggestions on how to treat the numbness in my big toe and the one next to it (right foot), on my own? The medical facility I use to go to is very prominent in the state I live in, but I just can't bring myself to pay them $250 again to practice on me.

    Stacy,

    We'd need to examine you to give advice.
