I'm having patch testing this week for a rash i've had for abut 18 months. Had a pretty instant reaction to one of the things, went for the first check today and one of the substances has caused a big reaction - very hot and red and itchy and swollen - and it turns out it's nickel.
I had no idea - dont' react to earings or anything - the rash is on my tummy and sides usually so i guess belts and buttons and underwire will be the cause?
Anyone else have this kind of reaction - what do you do about buttons on jeans etc?
And is nickel allergy only caused by actual contact or is nickel in foods as well?
