Ipod Rash

So sometime last year I developed a rash on my arm, it was a small light rash....nothing to worry about until I got some around my chest and stomach areas and still had no idea what was from...so last night there was a something on the news about iPods giving rashes to people from the Nickle around the iPod, so I looked it up and the rashes on google were like the ones I had then and the light one I have on my arm right now...its an allergic reaction to Nickle I think I just have a light reaction cause the pics on google were scary serious cases of the rash so you may want to Check it out just in case.
