Nickel sensitivity symptoms will often get worse (or start) when you get hot and sweaty because it’s the salts in perspiration that carry the nickel through your skin. If the below symptoms occur, you may be allergic to nickel (or potentially another metal – some people are allergic to aluminium or other metals).
A rash, itchy patch or redness/soreness which gets worse during the summer months is a good warning sign that sweat is combining with something and causing a reaction.
Remember symptoms can get worse and worse if you do nothing – if you don’t find out what you’re reacting to and deal with it.
Rash or itching under a bracelet or watch.
Rash, itching or redness below a necklace.
Rash or itching underneath a trouser (pants) pocket which you typically use to hold keys or coins. Note that the pocket fabric doesn’t protect you from the nickel – I know this first-hand since this was my first symptom of a nickel allergy.
This is a classic and common symptom – a rash on your belly – around the top of your jeans. Typically this can be a reaction to nickel in the button or rivet in your jeans. It’s also possible to get a reaction from a belt buckle – particularly if you wear it such that it touches your skin. It’s also possible to get a reaction through a shirt however.
Again, a common symptom, redness, itching, soreness, rash or blistering around an ear piercing. This can be the very first symptom of a nickel allergy when you pierce your ears for the first time and don’t ensure that the “healing” post is nickel free. The wound will fail to heal – and just get worse and worse.
Flaky skin or blistering next to glasses (spectacle/eyeglasses) frames.
