text: how do you get rid of the bump that's caused my your cartridge (top of ear) being pierced? it's been pierced for about 5-6 years now and i didn't have any problems with a bump before.  when i first got it pierced, i had a problem with a blood bubble, but that went away 5 years ago. yep - scar tissue.  you can certainly ask a dermatologist though!  you never know.  they might have a way to at least diminish the appearance of the scarring.
