The 39-year-old, from Sheffield, gets itchy sores on her palms when she handles coins containing nickel.
“It does make shopping a bit of a nightmare. Copper coins cause me the most trouble. They seem to have a very high quantity of nickel in them.
The palm of my hands will get severely itchy and irritable for the rest of the day.”
Emma first discovered she was allergic to nickel at the age of nine when a necklace she was given by her aunt left her with itchy hives.
