Guns and cartilage piercings do not mix, from experience.I have the top of my right ear done, I got it done with a gun. I can't wear earrings in it at all, because every time I do it flares up like crazy.Needle it. Just...needle it.
I have two cartilage piercings in my left ear. They didn't hurt to get them done (with a gun) but they were crazy sore for WEEKS afterward. Couldn't sleep on that side and heaven forbid my shirt brushed against it when getting dressed in the morning. OMG pain. They got infected several times before they finally healed. I was okay to wear earrings in them comfortably after almost a year. Then I took them out and didn't put them back in for a few weeks. They didn't grow shut, but they have grown intolerant to wearing earrings for more than an hour or two again.
I've always liked the idea of getting a tattoo, but, frankly, right now I shouldn't. I don't have a firm idea of what I want, nor where on my body I'd want to place it!
