What can I do to help my metal allergy?

So, I have a metal allergy. I don't know to what kinds of metal, but I do know that when my skin comes in contact with metal, especially if it's warm, damp or rusty, I can develop an itchy rash. This happens on my forearms in my grandpa's beat up truck and on the rough spots on my armrest in my 2001 Mazda. Is this allergy common? What kinds of metal do you think cause this the most? Anything I can avoid or do to help prevent/lessen symptoms?

Also, the other day, I smoked out of a glass pipe that had an aluminum foil screen in the bottom, and I developed a slight (but scary) allergic reaction. My eyes and fingers swelled up, and my throat got a little tight, and I was very shaky. It went away after a while with some Benadryl.

Another important one - some deodorants irritate my armpits because the main ingredient contains aluminum. Are there safe, metal-free deodorants no the market that provide a strong antiperspirant?

often the allergy is to nickel. try covering the areas of the vehicle with a cloth or moleskin type of material. talk to your dermatologist about other options. titanium is the best metal to use for jewelry, glasses, etc.
