I'm allergic to nickel as found in jewelry. can i wear chrome plated jewelry without itching or breaking out?

Chrome over nickel: Purely "chromed" jewelry should be fine, but some are actually chromium-plated over nickel(making it more durable), thus once the chromium is worn-off exposing nickel you can still have trouble. Typically the reaction is slow and so if you start to have any trouble with the chromed/nickeled product, stop using asap and you should be fine. Topical steroid helps the rash. Consult doc. Good luck.
