I have done my ears 4 times, 3 times myself and once at a piercing studio... and will again very soon

Also FWIW twice got my navel pierced (at a studio)... infected, despite all the care in the world both times.
Back to ears, I used Dettol wound wash solution and surgical spirit, ears were fine, better than the belly button

but was caught out in an embarrassing way... wife "you look ridiculous" aya... aah very soon that will all change
Maybe do the belly button again, and... cover it up showering!
