Video: How to Treat Big Toe Numbness and Callus Formation
A common big toe problem is a callus and/or numbness on the side of the big toe. This can cause pain on the side of the big toe along with a feeling of numbness and tingling.
What Causes Calluses and Numbness of the Big Toe?
A callus, pain or numbness of the big toe is caused by a jamming of the big toe joint during walking. This is called hallux limitus. When the big toe cannot move fully as you step forward, you are forced to roll off of the side of the toe. This pinches the skin and causes the callus. It can also irritate the nerve in the toe and cause numbness and pain. This condition is called “compressive peripheral neuritis”, which is an inflammation of the nerve in the toe due to excessive compression of the nerve.
Numb big toes and calluses on the big toe are also very common in patients with bunions. In fact, these problems are present in most patients with bunions. This is because patients with bunions are forced to roll over the side of the big toe – this pinches the skin causing the callus and numbness. But you don’t have to have a bunion for these problems to occur.
What is the Most Effective Treatment of Big Toe Calluses and Numbness?
Since a lack of motion of the big toe joint causes the big toe corn or callus, the best way to treat it is to use shoes and orthotics that enhance big toe motion. You want to use stable shoes (available on our shoe list). Custom orthotics can be prescribed specifically to give the big toe joint maximum motion in order to eliminate or reduce callus formation. For very best results and reduction of the callus, this requires a very specific orthotic called a “total contact orthotic”. Several studies have demonstrated that they can improve big toe motion. To be evaluated for orthotics to treat your big toe callus, make an appointment to see us in our Seattle foot and ankle clinic.
It is critical that any orthotic used to treat numbness or callus of the big toe works to enhance motion in the big toe joint. This is the only way to effectively reduce pressure on the medial side of the toe. The video below provides a full explanation of what either a custom or a prefabricated orthotic must do in order to treat this problem. (Note: This video was produced as an educational video for podiatrists and so it may be a bit technical).
What are Home Treatments for Big Toe Callus and Numb Big Toe?
Home treatments for calluses and neuritis of the big toe are focused on improving motion of the big toe joint and getting rid of the pressure on the side of the toe that leads to callus formation and numbness due to pressure on the nerve.
To improve motion of the big toe, you must support the arch and transfer pressure off of the big toe joint (see the video above for details on how this works).
This will act to improve motion of the big toe joint so that you are less likely to roll of over the side of the toe. OTC arch supports will not work as well as a custom orthotic because they don’t conform as close to your arch (see video), but will help. One that we have found has the best ability to reduce pressure on the big toe is the P3 Prefabricated Orthotic.
2. Use Arch Support Flip Flops
Around the house, don’t go barefoot. Use a sandal with an arch support. This will act to decrease pressure on your big toe joint. We recommend the Vionic Flip-flops and Sandals for its superior arch support.
Grinding away the callus will decrease the pressure that leads to pain and numbness. The easiest way is to use a electric grinder like the Pedinova. Use it after a bath or shower when the skin is soft.
Another option to get rid of the callus on your big toe is a exfoliating tool such as the Ped Egg. This takes longer than the Pedinova grinder, but it is less expensive.
An exfoliating cream will help get rid fo the thickened skin that is causing pain and numbness of the big toe. Put this on each night after you use the grinder or Ped Egg on your callus. The cream we most often recommend to our patients is Urea 40% such as this Urea Cream 40.
These callus and blister prevention patches are made of a material called Polytetrafloroethelene or PTFE. PTFE has an extremely low coefficient of friction so it can dramatically decrease the friction forces that lead to callus formation. In fact, PTFE was developed originally as a suture material for fragile structures like blood vessels and nerves. Because it causes so little friction it doesn’t harm these very thin and fragile structures.
PTFE is also available in a self-stick patch under the brand name Engo. Engo patches can be applied to the insole of the shoe or on top of an orthotic right under the big toe. Applying these patches will help to decrease friction and by doing so will help prevent the formation of calluses and blisters. Engo PTFE patches can also be applied inside the shoe in areas at risk of blistering. Just cut out the shape you need and then peel and stick. The Engo patch should extend about 1/4 inch beyond the edge of the of the callus. You can get Engo PTFE patches here.
