Alright, I have been doing my homework and know that a piercing gun is much more likely to lead to an infection than a hollow needle. My question lies within the type of earrings to pick out. I am severely allergic to nickel – it makes my ears swell and begin to produce puss within an hour!! The “stud” type earrings actually grew into one of my piercings, so which type of earring post should I use?
