This is the build up of thickened/hard skin caused by repetitive friction and/or pressure. It can have a yellow looking appearance and can be painful – sometimes causing a burning sensation. Normally found on the ball of the foot, bony prominences, heel area and around the big toe.
A podiatrist can gently remove the hard skin and can give advice on how to prevent the callus reoccurring. This may involve the use of insoles to re-distribute the pressure or padding. Another preventative measure is to cream your feet on a daily basis as this helps keep the skin hydrated and flexible preventing it from drying out.
