Corns

Updated: April 2021

Overview:

Corns are caused by pressure over a bony bump such as a claw toe in a tight fitting shoe. They are usually smaller and harder than a callus. Corns commonly occur on toes and under the ball of the foot. Once removed a corn may reoccur if the pressure causing the corn is not removed.

Signs or symptoms you may experience:

  • 2nd, 3rd or 4th toe painful, yellow, thickened skin on the top of the joint or tip of the toe especially while wearing tight fitting shoes.

  • 5th toe painful, yellow, thickened skin on the outside of the toe especially while wearing tight fitting shoes.

  • Under the ball of the foot painful, yellow, thickened skin especially when walking barefoot or on a hard surface.

  • Between any toes painful, white, thickened skin especially while wearing tight fitting shoes.

If it's not a corn, what else might it be?

  • Callus

  • Wart

  • Foreign body (more common plantar forefoot or heel)

Treatment options:

The aim of treatment is to remove your corn, reduce pressure and address any related issues.  Usually a combination of treatments will be required. While the aim of treatment is to resolve symptoms, some individuals may have no benefit or increased symptoms from some treatments. Cease these treatments and contact Inform Podiatry.

  • Corn debrided (removed) by Inform Podiatry, we do not recommend the use of corn or carnation pads due to the risk of increased pain and further injury.

  • Footwear advice to reduce pressure causing the corn.

  • Padding in shoes or on feet to reduce pressure causing the corn.

  • Moisturising cream to soften the corn (does not help corns between toes). Inform Podiatry recommends and sells Walker's urea 15 foot lotion.

  • Prefab or custom orthoses to improve foot function to reduce pressure causing the corn.

  • When non-surgical options have been trialled without satisfactory benefit, Inform Podiatry may recommend a referral for a surgical opinion.
