Yes, and that is actually the smart way to do it. If a piercer does it with a barbell and happens to put one on that is too short, and doesnt allow room for swelling, it will cause you to develop an "elf ear", which is caused by the barbell not allowing room for your ear to grow and swell. Once it heals, you can go back to your piercer and ask him to fit you with an Industrial barbell that fits your ear size.
If you are asking just about the barbell in say an industrial piercing, they can range from $35.00 to $65.00 depending on the material and quality of the barbell.
Well the barbell should be long enough so you can push your hand against your ear and flatten out the cartilage and it should still feel comfortable, like laying down and putting your head on a pillow. You should not feel the barbell pulling on your ear cartilage, if it does then you should go see your piercer and explain that the barbell is too short for reasonable and comfortable wear. If they are a good shop they will get it squared away for you without any hassle.
Go see your doctor, chances are good you are reacting to the barbell material (galvanic corrosion) your doctor will be able to help you out.
Length depends on your ear but they're usually 16ga or 14ga
You shouldn't put a barbell in your ear. It can cause injury, infection, and damage to your ear canal or eardrum. If you're looking for body jewelry for your ear, consider safe and appropriate options like earrings designed for ear piercings.
Amber Barbell goes by Ambie, and Mcbubbles.
I do not advise doing this yourself. Go back to your piercer; they are better equipped to remove it without causing too much damage.
Every time you take it out, which for msot is nightly.
The jewelry is probably too short/tight. Go see a piercer and have them check it out to be sure what it is exactly an for them to fit you with the proper length barbell :)
Get it the side that you don't sleep on. Industrials can be tricky to heal so get it on the ear that you'd touch less.
The barbell is too long for your mouth, step the barbell down and that should go away.
