Corns and Calluses: Treatment That Actually Works
Corns and calluses are thickened skin from pressure or friction. Calluses are diffuse (broad areas); corns are localized (often have central core). Treatment: identify and remove pressure source (the most important step), gentle filing, salicylic acid, professional debridement. NEVER cut corns yourself if diabetic — risk of infection and ulcer.
Causes
Pressure and friction on skin from: poorly fitted shoes (most common), foot deformities (bunions, hammertoes — pressure on prominences), abnormal gait, manual labor, walking barefoot. Calluses on bottom of foot suggest biomechanical issue. Calluses on top of toes suggest hammertoe pressure.
Treatment
1. Address pressure source — wider shoes, padding, custom orthotic. This is the most important step.
2. Soak feet 15 min warm water.
3. File gently with pumice or microplane.
4. Salicylic acid patches/liquid.
5. Moisturize daily (urea cream, AmLactin).
6. Professional debridement by podiatrist (covered by Medicare for diabetics).
Diabetic Considerations
NEVER use OTC corn removers if diabetic — acid can damage healthy tissue and cause ulcers. NEVER cut your own corns or calluses if you have neuropathy. Schedule professional foot care every 8-12 weeks. Calluses indicate pressure points that may progress to ulcers without intervention.
