I don't even know what most of those are!!
I went through a rebel stage and got the cartilage in my ear, my tongue and nipple done (over a period of a couple of years...). The ear was fine - on the left side and done with a gun. I'm pretty sure I had no issues with it.
The tongue swelling went down fast and the long bar kept getting caught in my teeth while I was talking, so I tried to change it in a McDonalds since it was driving me nuts and it bled everywhere... You should have seen the looks of people coming in trying to use the bathrooms. I think I put a few people off lunch...
My hands were shaking, but I eventually got the short bar in and it was soooooo much better! Healed easy.
Nipple was REALLY sore! Who woulda thought huh????
Getting it done was about a second of pain, but then afterwards, for ages, a slight bump would knock it and gee it was sore! It wasn't infected, just very sensitive!
Ear - that's nothing, you'll be fine
