What Happens When You Pierce Your Nose And You Get A Keloid?
I got a really big keloid on my nose- looked like I pierced a wart! Then I did my tragus(or however you spell it) and I got it there too! When I called my tattoo parlor- after my nose- they said put melaluca oil AKA tea tree oil on it twice a day- morning and night- and a big fat wart size keloid went away! It was all gone after about 6 weeks total! I caught my tragus piercing before it got outta hand and that went away really fast! Hope this helped you!!!
