A man who is living with a rare skin condition says he has suffered 'years of hell'.
Since he was a child, Alan Bentley, 63, has endured Olmsted Syndrome - a lifelong disorder causing hard callouses to form on his feet - which left him unable to walk.
The condition, also known as mutilating palmoplantar keratoderma (PPK), has caused Alan both physical and mental pain throughout his life.
