When I wear my belt, there is a metal panel in the front. whenever my belly touches the metal a period of time, the skin is irritated with red spot.
Does anyone have any suggestions on what cause my belly sensitive?
Thanks in advance for any suggestions

sensitivity is general term ; it is a matter of histamine antigens and . so on, metal is sub-category of it. i also have sensitivity for Cu, Ag, somewhat Fe so i don't wear even a watch and i hold my belt buckle in trouser  and make it at side not facing abdomen so that it don't touch my skin.

Could you please tell me more about what histamine antigens are? so is my skin sensitivity because of any kind of chemical reaction?
Thanks in advance for any suggestions
