one group of people who are very much overrepresented
There is one group of people who are very much overrepresented when it comes to nickel and copper allergy.
It is those who have been, at some point in their life, wearing braces or some other similar metal orthodontics placed in their mouth by an orthodontist.
Modern wires used by orthodontists are often made from stainless steel, nickel, titanium, molybdenum, copper, and traces of many other rare metals.
Wire you have in your mouth may actually contain nickel !!!!!!!
Nickel allergy have already been associated with EC in several people posting on this forum.
Have you ever been tested for nickel allergy ?
Your problem may be oral allergy syndrome, same symptoms as EC.
