I have the metal allergy problem too, stainless steel always worked for me, also you can get silicon jewelry after it heals. I've had pretty much everything pierced on my face at some time or another but I only have a bunch in my ears now. I'm over piercings, so I don't want any more
My ears twice & my tongue. I had more but I either took them out or they rejected. I'm probably gonna get my belly pierced again (both top & bottom) & maybe a couple of ear piercings. & I thought about a nose stud.
