As a piercing girlie, I'm wondering if the girls who smell afterwards even with the incision healed... it's not actually healed. With piercings, they heal outside in. So even if that outer layer of skin looks sealed and healed, inside could not be, and that's concerning to me. You should not take new infected piercings out, because the outside can heal up and seal that infection inside and not give it room to breathe. So yeah it sounds not just unpleasant but possibly dangerous, these girls thinking their healed but with unpleasant side effects, when maybe there's an infection they can't even see
I'm 75 years old and I want to tell all young ladies to remember "All cuts leave a scar". Over time those scars can grow, stretch and get thicker. It's a damage to your once perfect skin. It will never disappear it's always a cut, a scar so think twice or three times before you decide.
