What is Clavus?
Clavus, more commonly known as a corn, is a condition where skin thickens and hardens over a specific area, often the foot, due to chronic pressure.
Typical Symptoms of Clavus
- Hard or stiff skin
- Skin over my fingers are hardened
- Skin lumps
- Skin problem on the feet, beyond the ankle
- Rough and scaly skin
- Skin is thick and rough/scaly
- Skin problem of the legs, in the area between thigh and ankle
- Pain in the sole of your foot
Diagnostic Questions for Clavus
Your doctor may ask these questions to check for this disease:
- Have you noticed any hard or stiff areas on your skin?
- Is your skin getting harder from fingertip to back of your hand?
- Have you noticed any lumps on your skin?
- Do your foot problems affect the skin beyond the ankle?
- Do you have rough and scaly skin?
Treatment of Clavus
Corn plasters or a simple procedure can remove the hard center. However, lifestyle changes like switching to well-fitting shoes are needed to prevent corns from returning.
