My ear holes never healed right - I'm not sure if it was an allergy or what, but no amount of time (and no level of gold purity) ever stopped the crusty discharge or the tendency to close up if I went for more than 2-3 days not wearing earrings. So when I wanted to wear them, after I gave up keeping them in all the time and was only wearing them occasionally, I had to stab the earrings through the layer of scar tissue in the center. Which required a mirror.
