Do you have Callus on your feet? This is a localized area of thicker skin. It can be yellow in colour and feel hard to the touch. Causes for callus are usually due to pressure and repetitive friction. Poorly fitting shoes can increase the presentation of callus. The body responds to pressure by producing more skin to this area to protect you from skin breakdown. If the pressure and friction do not stop there is a risk of skin breakdown under the callus this is called an ulcer. Other causes of callus are injury, scar formation, medical conditions and eczema or psoriasis. Think Feet located at 169 Front St. S. Orillia can help you treat this call 705-329-0908.
