A sensible approach: Make sure that the shoe you are wearing is the correct size. Cutting down the skin helps at times when done by a Podiatrist. Diabetics see a DPM Keep the area free of irritation when possible. Silicone gel pads that can be purchased which fit over the toe offer great comfort Avoid over the counter medicated pads . They contain a weak acid and can damage the skin If no relief see a PODIATRIST.
