Although corns are not serious, they can cause irritation, inflammation or even ulceration. If you experience severe inflammation or pain, you should seek medical advice.
If you are unsure if what you have is a corn, you are advised to consult a doctor or other appropriate healthcare professional.
Frequently reappearing corns might be caused by foot abnormalities, such as deformities, structural abnormalities of the bones, poor bone alignment or an abnormal gait. If you are concerned by the frequency or persistency of your corns, you might want to visit a doctor or podiatrist in order to rule out or detect any of these underlying causes. In these cases a specific padding or shoe insert might help you to prevent corns from reappearing. In rare cases, surgery might be necessary.
